Stefan Reinauer <stefan.reinauer at coreboot dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target| |nds32le-elf Host| |Darwin 15.4.0 --- Comment #2 from Stefan Reinauer <stefan.reinauer at coreboot dot org> --- The environment is Mac OS X El Capitan (Darwin 15.4.0) cross compiler build for nds32le-elf fails when building libgcc. So far, I tracked the issue down to cc1 crashing when compiling divfs3.c (or even the attached minimized example of it) ------------- 8< -------------------------- 8< ------------------- ./build-nds32le-elf-GCC/gcc/cc1 divsf3.c __divsf3 Analyzing compilation unit Performing interprocedural optimizations <*free_lang_data> <visibility> <build_ssa_passes> <opt_local_passes> <free-inline-summary> <emutls> <whole-program> <inline>Assembling functions: __divsf3Abort trap: 6 ------------- 8< -------------------------- 8< ------------------- Debugger output: ------------- 8< -------------------------- 8< ------------------- lldb ./build-nds32le-elf-GCC/gcc/cc1 (lldb) target create "./build-nds32le-elf-GCC/gcc/cc1" Current executable set to './build-nds32le-elf-GCC/gcc/cc1' (x86_64).
