-The perl scripts in this directory are my 'hack' to generate
-multiple different assembler formats via the one origional script.
-
-The way to use this library is to start with adding the path to this directory
-and then include it.
-
-push(@INC,"perlasm","../../perlasm");
-require "x86asm.pl";
-
-The first thing we do is setup the file and type of assember
-
-&asm_init($ARGV[0],$0);
-
-The first argument is the 'type'. Currently
-'cpp', 'sol', 'a.out', 'elf' or 'win32'.
-Argument 2 is the file name.
-
-The reciprocal function is
-&asm_finish() which should be called at the end.
-
-There are 2 main 'packages'. x86ms.pl, which is the microsoft assembler,
-and x86unix.pl which is the unix (gas) version.
-
-Functions of interest are:
-&external_label("des_SPtrans"); declare and external variable
-&LB(reg); Low byte for a register
-&HB(reg); High byte for a register
-&BP(off,base,index,scale) Byte pointer addressing
-&DWP(off,base,index,scale) Word pointer addressing
-&stack_push(num) Basically a 'sub esp, num*4' with extra
-&stack_pop(num) inverse of stack_push
-&function_begin(name,extra) Start a function with pushing of
- edi, esi, ebx and ebp. extra is extra win32
- external info that may be required.
-&function_begin_B(name,extra) Same as norma function_begin but no pushing.
-&function_end(name) Call at end of function.
-&function_end_A(name) Standard pop and ret, for use inside functions
-&function_end_B(name) Call at end but with poping or 'ret'.
-&swtmp(num) Address on stack temp word.
-&wparam(num) Parameter number num, that was push
- in C convention. This all works over pushes
- and pops.
-&comment("hello there") Put in a comment.
-&label("loop") Refer to a label, normally a jmp target.
-&set_label("loop") Set a label at this point.
-&data_word(word) Put in a word of data.
-
-So how does this all hold together? Given
-
-int calc(int len, int *data)
- {
- int i,j=0;
-
- for (i=0; i<len; i++)
- {
- j+=other(data[i]);
- }
- }
-
-So a very simple version of this function could be coded as
-
- push(@INC,"perlasm","../../perlasm");
- require "x86asm.pl";
-
- &asm_init($ARGV[0],"cacl.pl");
-
- &external_label("other");
-
- $tmp1= "eax";
- $j= "edi";
- $data= "esi";
- $i= "ebp";
-
- &comment("a simple function");
- &function_begin("calc");
- &mov( $data, &wparam(1)); # data
- &xor( $j, $j);
- &xor( $i, $i);
-
- &set_label("loop");
- &cmp( $i, &wparam(0));
- &jge( &label("end"));
-
- &mov( $tmp1, &DWP(0,$data,$i,4));
- &push( $tmp1);
- &call( "other");
- &add( $j, "eax");
- &pop( $tmp1);
- &inc( $i);
- &jmp( &label("loop"));
-
- &set_label("end");
- &mov( "eax", $j);
-
- &function_end("calc");
-

-# Ascetic x86_64 AT&T to MASM/NASM assembler translator by <appro>.
-#
-# Why AT&T to MASM and not vice versa? Several reasons. Because AT&T
-# format is way easier to parse. Because it's simpler to "gear" from
-# Unix ABI to Windows one [see cross-reference "card" at the end of
-# file]. Because Linux targets were available first...
-#
-# In addition the script also "distills" code suitable for GNU
-# assembler, so that it can be compiled with more rigid assemblers,
-# such as Solaris /usr/ccs/bin/as.
-#
-# This translator is not designed to convert *arbitrary* assembler
-# code from AT&T format to MASM one. It's designed to convert just
-# enough to provide for dual-ABI OpenSSL modules development...
-# There *are* limitations and you might have to modify your assembler
-# code or this script to achieve the desired result...
-#
-# Currently recognized limitations:
-#
-# - can't use multiple ops per line;
-#
-# Dual-ABI styling rules.
-#
-# 1. Adhere to Unix register and stack layout [see cross-reference
-# ABI "card" at the end for explanation].
-# 2. Forget about "red zone," stick to more traditional blended
-# stack frame allocation. If volatile storage is actually required
-# that is. If not, just leave the stack as is.
-# 3. Functions tagged with ".type name,@function" get crafted with
-# unified Win64 prologue and epilogue automatically. If you want
-# to take care of ABI differences yourself, tag functions as
-# ".type name,@abi-omnipotent" instead.
-# 4. To optimize the Win64 prologue you can specify number of input
-# arguments as ".type name,@function,N." Keep in mind that if N is
-# larger than 6, then you *have to* write "abi-omnipotent" code,
-# because >6 cases can't be addressed with unified prologue.
-# 5. Name local labels as .L*, do *not* use dynamic labels such as 1:
-# (sorry about latter).
-# 6. Don't use [or hand-code with .byte] "rep ret." "ret" mnemonic is
-# required to identify the spots, where to inject Win64 epilogue!
-# But on the pros, it's then prefixed with rep automatically:-)
-# 7. Stick to explicit ip-relative addressing. If you have to use
-# GOTPCREL addressing, stick to mov symbol@GOTPCREL(%rip),%r??.
-# Both are recognized and translated to proper Win64 addressing
-# modes. To support legacy code a synthetic directive, .picmeup,
-# is implemented. It puts address of the *next* instruction into
-# target register, e.g.:
-#
-# .picmeup %rax
-# lea .Label-.(%rax),%rax
-#
-# 8. In order to provide for structured exception handling unified
-# Win64 prologue copies %rsp value to %rax. For further details
-# see SEH paragraph at the end.
-# 9. .init segment is allowed to contain calls to functions only.
-# a. If function accepts more than 4 arguments *and* >4th argument
-# is declared as non 64-bit value, do clear its upper part.

-# Point is that at apparently no occasion Windows kernel would alter

-#

-# Win64 SEH, Structured Exception Handling.
-#
-# Unlike on Unix systems(*) lack of Win64 stack unwinding information
-# has undesired side-effect at run-time: if an exception is raised in
-# assembler subroutine such as those in question (basically we're
-# referring to segmentation violations caused by malformed input
-# parameters), the application is briskly terminated without invoking
-# any exception handlers, most notably without generating memory dump
-# or any user notification whatsoever. This poses a problem. It's
-# possible to address it by registering custom language-specific
-# handler that would restore processor context to the state at
-# subroutine entry point and return "exception is not handled, keep
-# unwinding" code. Writing such handler can be a challenge... But it's
-# doable, though requires certain coding convention. Consider following
-# snippet:
-#
-# .type function,@function
-# function:
-# movq %rsp,%rax # copy rsp to volatile register
-# pushq %r15 # save non-volatile registers
-# pushq %rbx
-# pushq %rbp
-# movq %rsp,%r11
-# subq %rdi,%r11 # prepare [variable] stack frame
-# andq $-64,%r11
-# movq %rax,0(%r11) # check for exceptions
-# movq %r11,%rsp # allocate [variable] stack frame
-# movq %rax,0(%rsp) # save original rsp value
-# magic_point:
-# ...
-# movq 0(%rsp),%rcx # pull original rsp value
-# movq -24(%rcx),%rbp # restore non-volatile registers
-# movq -16(%rcx),%rbx
-# movq -8(%rcx),%r15
-# movq %rcx,%rsp # restore original rsp
-# ret
-# .size function,.-function
-#
-# The key is that up to magic_point copy of original rsp value remains
-# in chosen volatile register and no non-volatile register, except for
-# rsp, is modified. While past magic_point rsp remains constant till
-# the very end of the function. In this case custom language-specific
-# exception handler would look like this:
-#
-# EXCEPTION_DISPOSITION handler (EXCEPTION_RECORD *rec,ULONG64 frame,
-# CONTEXT *context,DISPATCHER_CONTEXT *disp)
-# { ULONG64 *rsp = (ULONG64 *)context->Rax;
-# if (context->Rip >= magic_point)
-# { rsp = ((ULONG64 **)context->Rsp)[0];
-# context->Rbp = rsp[-3];
-# context->Rbx = rsp[-2];
-# context->R15 = rsp[-1];
-# }
-# context->Rsp = (ULONG64)rsp;
-# context->Rdi = rsp[1];
-# context->Rsi = rsp[2];
-#
-# memcpy (disp->ContextRecord,context,sizeof(CONTEXT));
-# RtlVirtualUnwind(UNW_FLAG_NHANDLER,disp->ImageBase,
-# dips->ControlPc,disp->FunctionEntry,disp->ContextRecord,
-# &disp->HandlerData,&disp->EstablisherFrame,NULL);
-# return ExceptionContinueSearch;
-# }
-#
-# It's appropriate to implement this handler in assembler, directly in
-# function's module. In order to do that one has to know members'
-# offsets in CONTEXT and DISPATCHER_CONTEXT structures and some constant
-# values. Here they are:
-#
-# CONTEXT.Rax 120
-# CONTEXT.Rcx 128
-# CONTEXT.Rdx 136
-# CONTEXT.Rbx 144
-# CONTEXT.Rsp 152
-# CONTEXT.Rbp 160
-# CONTEXT.Rsi 168
-# CONTEXT.Rdi 176
-# CONTEXT.R8 184
-# CONTEXT.R9 192
-# CONTEXT.R10 200
-# CONTEXT.R11 208
-# CONTEXT.R12 216
-# CONTEXT.R13 224
-# CONTEXT.R14 232
-# CONTEXT.R15 240
-# CONTEXT.Rip 248
-# CONTEXT.Xmm6 512
-# sizeof(CONTEXT) 1232
-# DISPATCHER_CONTEXT.ControlPc 0
-# DISPATCHER_CONTEXT.ImageBase 8
-# DISPATCHER_CONTEXT.FunctionEntry 16
-# DISPATCHER_CONTEXT.EstablisherFrame 24
-# DISPATCHER_CONTEXT.TargetIp 32
-# DISPATCHER_CONTEXT.ContextRecord 40
-# DISPATCHER_CONTEXT.LanguageHandler 48
-# DISPATCHER_CONTEXT.HandlerData 56
-# UNW_FLAG_NHANDLER 0
-# ExceptionContinueSearch 1
-#
-# In order to tie the handler to the function one has to compose
-# couple of structures: one for .xdata segment and one for .pdata.
-#
-# UNWIND_INFO structure for .xdata segment would be
-#
-# function_unwind_info:
-# .byte 9,0,0,0
-# .rva handler
-#
-# This structure designates exception handler for a function with
-# zero-length prologue, no stack frame or frame register.
-#
-# To facilitate composing of .pdata structures, auto-generated "gear"
-# prologue copies rsp value to rax and denotes next instruction with
-# .LSEH_begin_{function_name} label. This essentially defines the SEH
-# styling rule mentioned in the beginning. Position of this label is
-# chosen in such manner that possible exceptions raised in the "gear"
-# prologue would be accounted to caller and unwound from latter's frame.
-# End of function is marked with respective .LSEH_end_{function_name}
-# label. To summarize, .pdata segment would contain
-#
-# .rva .LSEH_begin_function
-# .rva .LSEH_end_function
-# .rva function_unwind_info
-#
-# Reference to functon_unwind_info from .xdata segment is the anchor.
-# In case you wonder why references are 32-bit .rvas and not 64-bit
-# .quads. References put into these two segments are required to be
-# *relative* to the base address of the current binary module, a.k.a.
-# image base. No Win64 module, be it .exe or .dll, can be larger than
-# 2GB and thus such relative references can be and are accommodated in
-# 32 bits.
-#
-# Having reviewed the example function code, one can argue that "movq
-# %rsp,%rax" above is redundant. It is not! Keep in mind that on Unix
-# rax would contain an undefined value. If this "offends" you, use
-# another register and refrain from modifying rax till magic_point is
-# reached, i.e. as if it was a non-volatile register. If more registers
-# are required prior [variable] frame setup is completed, note that
-# nobody says that you can have only one "magic point." You can
-# "liberate" non-volatile registers by denoting last stack off-load
-# instruction and reflecting it in finer grade unwind logic in handler.
-# After all, isn't it why it's called *language-specific* handler...
-#
-# Attentive reader can notice that exceptions would be mishandled in
-# auto-generated "gear" epilogue. Well, exception effectively can't
-# occur there, because if memory area used by it was subject to
-# segmentation violation, then it would be raised upon call to the
-# function (and as already mentioned be accounted to caller, which is
-# not a problem). If you're still not comfortable, then define tail
-# "magic point" just prior ret instruction and have handler treat it...
-#
-# (*) Note that we're talking about run-time, not debug-time. Lack of
-# unwind information makes debugging hard on both Windows and
-# Unix. "Unlike" referes to the fact that on Unix signal handler
-# will always be invoked, core dumped and appropriate exit code
-# returned to parent (for user notification).
