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). diff --git a/openssl/crypto/perlasm/x86asm.pl b/openssl/crypto/perlasm/x86asm.pl deleted file mode 100644 index 28080caa..00000000 --- a/openssl/crypto/perlasm/x86asm.pl +++ /dev/null @@ -1,207 +0,0 @@ -#!/usr/bin/env perl - -# require 'x86asm.pl';
