Hi all,
===> gcc 4.1.1 (release), AIX 5.3
What else does the -O1 flag turn on besides the options listed in the following
document? Is there any way to turn these on/off incrementally?
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Optimize-Options.html#Optimize-Options
I'm trying to isolate the cause of excessively long compile times for a c++ code
when both debug information (-g) and any optimization level (O1/O2/O3) are enabled.
The compile time is fine when I explicitly pass all the flags that -O1 is
documented to engage along with -g. However, it blows up (in the assembler, up
to 10x) when I call -O1 directly.
Thanks,
--Nathan
