[yocto] How to build xgcc with debug information ?

[Pedro Erencia]

*Hi all, I'm having a hard time trying to do what the title says.I was
using yocto to create a qt4e-image and got an Internal compiler error |
/home/pedro/poky/build/tmp/work-shared/gcc-4.6.3+svnr184847-r29/gcc-4_6-branch/libgcc/../gcc/libgcc2.c:
In function '__negdi2':|
/home/pedro/poky/build/tmp/work-shared/gcc-4.6.3+svnr184847-r29/gcc-4_6-branch/libgcc/../gcc/libgcc2.c:72:1:
internal compiler error: Segmentation fault| Please submit a full bug
report,*
*Then i wanted to run gdb on xgcc but it didn't have debug symbols, so i
added this to gcc-cross-initial.inc and gcc-cross-intermediate.inc*

*CFLAGS += "-g"*

*And it actually generated the debug symbols but some variable were
stripped by the -O2 optimization. *
*( the error was found on line 86 on ira-conflicts, btw).*

*I have not managed to remove the -O2, I've tried changing to CFLAGS += "-g
-Og", but now it doesn't even generate a debug build :) So, before i mess
it even more, i'd like to know what has to be done to properly create a
debug-friendly xgcc. *


*Thanks :)*
