Is there cc which support debugging of optimized 64-bit code

[김유성]

In my machine, cc compiler work well with '-g', '-O' options together when target binary is 32 bit.
But when target binary is 64 bit, it doesn't work.
Is there any cc compiler that support '-g', '-O' option together?

environment:
#uname -a
HP-UX tmaxh4 B.11.11 U 9000/800 2618835799

Hi

I really don't think is possible since the code, which the compiler generates is purly optimized to the 64 bit cpu, which does some runtime descisions, and might modify the way the code works, so debugging information might not be too helpful.
If it calms you down - debugging and optimization do not dance together on other OS's like Sun Solaris.
Thanks

If you are compiling on a PA64 machine and seeing this error message then try using the latest compilers.

The problem is not reproducible with my compiler cc version -
