Hi Guys,
noted trying to rebuild guile 1.8.8.
The following piece of code in the past
was setting SCM_I_GSC_STACK_GROWS_UP=0
and now produces SCM_I_GSC_STACK_GROWS_UP=1
I assume some change in the gcc compiler is causing the issue.
I presume most of the programs and libraries do not care,
but some special one like guile crashes during build for this issue,
so be aware.
Regards
Marco
If the compiler is gcc or clang:
__attribute__(__noinline__)
thanks Glenn,
as
__attribute__((__noinline__))
it seems to work
for all variant of -Ox
int
find_stack_direction ()
{
...
}
Cheers, Glenn
Can somebody explain the weird behaviour previously described, address
of the char going up 1 byte a few times, then skipping down, etc, and
why recursive calls are affected at all by inline, and what gcc thinks
it can optimize in that case?
