761# Win64 SEH, Structured Exception Handling.
762#
763# Unlike on Unix systems(*) lack of Win64 stack unwinding information
764# has undesired side-effect at run-time: if an exception is raised in
765# assembler subroutine such as those in question (basically we're
766# referring to segmentation violations caused by malformed input
767# parameters), the application is briskly terminated without invoking
768# any exception handlers, most notably without generating memory dump
769# or any user notification whatsoever. This poses a problem. It's
770# possible to address it by registering custom language-specific
771# handler that would restore processor context to the state at
772# subroutine entry point and return "exception is not handled, keep
773# unwinding" code. Writing such handler can be a challenge... But it's
774# doable, though requires certain coding convention. Consider following
775# snippet:
776#
777# .type function,@function
778# function:
779# movq %rsp,%rax # copy rsp to volatile register
780# pushq %r15 # save non-volatile registers
781# pushq %rbx
782# pushq %rbp
783# movq %rsp,%r11
784# subq %rdi,%r11 # prepare [variable] stack frame
785# andq $-64,%r11
786# movq %rax,0(%r11) # check for exceptions
787# movq %r11,%rsp # allocate [variable] stack frame
788# movq %rax,0(%rsp) # save original rsp value
789# magic_point:
790# ...
791# movq 0(%rsp),%rcx # pull original rsp value
792# movq -24(%rcx),%rbp # restore non-volatile registers
793# movq -16(%rcx),%rbx
794# movq -8(%rcx),%r15
795# movq %rcx,%rsp # restore original rsp
796# ret
797# .size function,.-function
798#
799# The key is that up to magic_point copy of original rsp value remains
800# in chosen volatile register and no non-volatile register, except for
801# rsp, is modified. While past magic_point rsp remains constant till
802# the very end of the function. In this case custom language-specific
803# exception handler would look like this:
804#
805# EXCEPTION_DISPOSITION handler (EXCEPTION_RECORD *rec,ULONG64 frame,
806# CONTEXT *context,DISPATCHER_CONTEXT *disp)
807# { ULONG64 *rsp = (ULONG64 *)context->Rax;
808# if (context->Rip >= magic_point)
809# { rsp = ((ULONG64 **)context->Rsp)[0];
810# context->Rbp = rsp[-3];
811# context->Rbx = rsp[-2];
812# context->R15 = rsp[-1];
813# }
814# context->Rsp = (ULONG64)rsp;
815# context->Rdi = rsp[1];
816# context->Rsi = rsp[2];
817#
818# memcpy (disp->ContextRecord,context,sizeof(CONTEXT));
819# RtlVirtualUnwind(UNW_FLAG_NHANDLER,disp->ImageBase,
820# dips->ControlPc,disp->FunctionEntry,disp->ContextRecord,
821# &disp->HandlerData,&disp->EstablisherFrame,NULL);
822# return ExceptionContinueSearch;
823# }
824#
825# It's appropriate to implement this handler in assembler, directly in
826# function's module. In order to do that one has to know members'
827# offsets in CONTEXT and DISPATCHER_CONTEXT structures and some constant
828# values. Here they are:
829#
830# CONTEXT.Rax 120
831# CONTEXT.Rcx 128
832# CONTEXT.Rdx 136
833# CONTEXT.Rbx 144
834# CONTEXT.Rsp 152
835# CONTEXT.Rbp 160

839# CONTEXT.R9 192

841# CONTEXT.R11 208
842# CONTEXT.R12 216
843# CONTEXT.R13 224
844# CONTEXT.R14 232
845# CONTEXT.R15 240
846# CONTEXT.Rip 248
847# CONTEXT.Xmm6 512
848# sizeof(CONTEXT) 1232
849# DISPATCHER_CONTEXT.ControlPc 0
850# DISPATCHER_CONTEXT.ImageBase 8
851# DISPATCHER_CONTEXT.FunctionEntry 16
852# DISPATCHER_CONTEXT.EstablisherFrame 24
853# DISPATCHER_CONTEXT.TargetIp 32
854# DISPATCHER_CONTEXT.ContextRecord 40
855# DISPATCHER_CONTEXT.LanguageHandler 48
856# DISPATCHER_CONTEXT.HandlerData 56
857# UNW_FLAG_NHANDLER 0
858# ExceptionContinueSearch 1
859#
860# In order to tie the handler to the function one has to compose
861# couple of structures: one for .xdata segment and one for .pdata.
862#
863# UNWIND_INFO structure for .xdata segment would be
864#
865# function_unwind_info:
866# .byte 9,0,0,0
867# .rva handler
868#
869# This structure designates exception handler for a function with
870# zero-length prologue, no stack frame or frame register.
871#
872# To facilitate composing of .pdata structures, auto-generated "gear"
873# prologue copies rsp value to rax and denotes next instruction with
874# .LSEH_begin_{function_name} label. This essentially defines the SEH
875# styling rule mentioned in the beginning. Position of this label is
876# chosen in such manner that possible exceptions raised in the "gear"
877# prologue would be accounted to caller and unwound from latter's frame.
878# End of function is marked with respective .LSEH_end_{function_name}
879# label. To summarize, .pdata segment would contain
880#
881# .rva .LSEH_begin_function
882# .rva .LSEH_end_function
883# .rva function_unwind_info
884#
885# Reference to functon_unwind_info from .xdata segment is the anchor.
886# In case you wonder why references are 32-bit .rvas and not 64-bit
887# .quads. References put into these two segments are required to be
888# *relative* to the base address of the current binary module, a.k.a.
889# image base. No Win64 module, be it .exe or .dll, can be larger than
890# 2GB and thus such relative references can be and are accommodated in
891# 32 bits.
892#
893# Having reviewed the example function code, one can argue that "movq
894# %rsp,%rax" above is redundant. It is not! Keep in mind that on Unix
895# rax would contain an undefined value. If this "offends" you, use
896# another register and refrain from modifying rax till magic_point is
897# reached, i.e. as if it was a non-volatile register. If more registers
898# are required prior [variable] frame setup is completed, note that
899# nobody says that you can have only one "magic point." You can
900# "liberate" non-volatile registers by denoting last stack off-load
901# instruction and reflecting it in finer grade unwind logic in handler.
902# After all, isn't it why it's called *language-specific* handler...
903#
904# Attentive reader can notice that exceptions would be mishandled in
905# auto-generated "gear" epilogue. Well, exception effectively can't
906# occur there, because if memory area used by it was subject to
907# segmentation violation, then it would be raised upon call to the
908# function (and as already mentioned be accounted to caller, which is
909# not a problem). If you're still not comfortable, then define tail
910# "magic point" just prior ret instruction and have handler treat it...
911#
912# (*) Note that we're talking about run-time, not debug-time. Lack of
913# unwind information makes debugging hard on both Windows and
914# Unix. "Unlike" referes to the fact that on Unix signal handler
915# will always be invoked, core dumped and appropriate exit code
916# returned to parent (for user notification).
