Re: local variable alignment on Solaris/SPARC, with gcc 4.x

Just a final follow-up on this issue:
- I tried with gcc 4.2.1 and it didn't make any difference
- I poked around with compiler options etc. also to no avail

I finally broke-down and rebuilt gcc with debug symbols. After some head-scratching, I found that the stack allocation routines in gcc 4.x are quite different than in 3.x. A new macro LOCAL_ALIGNMENT is used to override alignment for stack allocated variables. Unfortunately, this macro is not defined for the SPARC (only for the x86).

I opened the following bug report to report this and see if it can be corrected:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33594

Anyway, thanks for your suggestions...

Hi Amruth,

I assume that testFunc2 is in testFunc2.c, testFunc is in TestFunc.c, and main is in main.c.  And somewhere (either in the C source, or a header) there is a 'extern void testFunc2();' and 'extern void testFunc();' declared.

And they are being compiled:
gcc -O2 main.c testFunc.c testFunc2.c

Is that assumption correct?

HTH,
