With no further objections, I've uploaded the patch to
https://bugs.freepascal.org/view.php?id=32637 - it is
prefixed with "STACK_FRAME_" - ignore the other 3 patches, as they're incorrect.

Would code like this be correct?
Procedure FillWord(var x; count: SizeInt; value: Word); assembler; nostackframe;
asm
{ win64: rcx dest, rdx count, r8w value
linux: rdi dest, rsi count, dx value }
{$ifdef win64}
push%rdi
.seh_pushreg %rdi
.seh_endprologue
cmp $0x0, %rdx
Ooh right, okay. Thanks for that Sergei. I just put it in somewhat blindly
because the compiler inserts it
for Pascal code after the normal prologue after creating a stack frame, but
complained and threw an error if
I used .seh_pushreg but then neglected to use .seh_endprologue. I agree

Hi everyone,
Re: https://bugs.freepascal.org/view.php?
id=32637
I have now modified my assembler code that
contains ".seh_pushreg %rdi" after each
"push %rdi" instruction (the Linux
versions don't actually push any registers
because the required %rdi register is
volatile on that platform).
Hi everyone,
Re: https://bugs.freepascal.org/view.php?id=32637
I apologise for my slight outburst. I didn't quite appreciate Thaddy's response
when I asked how to get SEH to
keep track of pushed registers (

I'm guessing my code is not correct or causes problems. I haven't had much
luck in finding a straight answer
regarding proper exception handling with assembler code (where correcting
non-volatile registers and stack
space are concerned), although I'll keep trying. I tried asking on the
10 matches
