Hi jasonwucj, I actually see my CFLAGS variables being used as expected, but no debug information is generated. If I pass CFLAGS=-gstabs I actually do get debug info, just not with -g. Why won't it produce dwarf debug information for libgcc? --- Dan Schatzberg
Hi, Dan, I suggest you can try setting HOST_LIBGCC2_CFLAGS first, see if it does achieve your requirement. To figure out why it doesn't produce dwarf debug information, I think it would be good to preserve your libgcc building process (e.g. make all-target-libgcc | tee make-log). Then, check the process to understand how it issues options to compile libgcc stuff, comparing the options against the variables in libgcc/Makefile.in, especially the variables CFLAGS, LIBGCC2_DEBUG_CFLAGS, LIBGCC2_CFLAGS, HOST_LIBGCC2_CFLAGS, and INTERNAL_CFLAGS, I believe you will find out why it is not good to set -g3 in CFLAGS for building libgcc. :) Best regards, jasonwucj
