Hello,
Can anybody explain how the register allocation is handled in GCC? Is it
done together with the general register allocation? or GCC has a separate phase
to handle them separately?
Any pointer to the source code that I can take a look? Thanks
Peng

Hi,
I have following questions and would appreciate any comment. Thanks you
very much.
1. How to build a debugable version of GCC? I tried to set CFLGAS &
CXXFLAGS to "-O0 -g -fno-inline" in my configure command line, but it seems it
doesn't work. I manually modify all the Makefiles
Hi,
I cannot find the declaration of INTEGER_CST. Seems it is generated during
the build process? Is there a way to let the building process to generate all
the source files that are needed for a smooth source browsing? Thanks

Hello,
I did a quick search on "gcc internal" document and cannot find any
explanation about the field meaning of struct tree_type. I am trying to use
typedef to introduce some new aggregrate types that my gcc can handle. And I
want to mark these types so that I can handle these types sp
33 minutes to 39 second? that sounds a drastic improvement.
The performance improvement is also amazing.
You can try to divide your program into subphases and measure
the biggest change in time and then focus on parts that contribute
to the most improvement. Sometimes it is can be done quickly
