Subject: Re: [4.0 Regression] Ada Bootstrap failures on powerpc-darwin with undefined symbol (__Unwind_fallback_frame_state_for) As a workaround, I've changed all instances of -lgcc -lgcc_eh in the specs file to -lgcc_eh -lgcc -lgcc_eh. With this change, the bootstrap got further along: ../../xgcc -c -I./ -I../rts -I. -I/vol/gnu/src/gcc/gcc-dist/gcc/ada -B../../ -O2 -g -O2 -gnatpg -gnata -I- /vol/gnu/src/gcc/gcc-dist/gcc/ada/makegpr.adb +===========================GNAT BUG DETECTED==============================+ | 4.0.0 20041119 (experimental) (powerpc-apple-darwin7.6.0) Bus error | | Error detected at makegpr.adb:4159:23 | Program received signal EXC_BAD_ACCESS, Could not access memory. 0x004e9650 in initializer_zerop (init=0x4469dcc0) at /vol/gnu/src/gcc/gcc-dist/gcc/tree.c:5834 (gdb) where #0 0x004e9650 in initializer_zerop (init=0x4469dcc0) at /vol/gnu/src/gcc/gcc-dist/gcc/tree.c:5834 #1 0x004e97dc in initializer_zerop (init=0x4469dcc0) at /vol/gnu/src/gcc/gcc-dist/gcc/tree.c:5870 #2 0x004e97dc in initializer_zerop (init=0x4469dcc0) at /vol/gnu/src/gcc/gcc-dist/gcc/tree.c:5870 #3 0x004fb574 in assemble_variable (decl=0xc659a8, top_level=115, at_end=6317412, dont_output_data=1147788480) at /vol/gnu/src/gcc/gcc-dist/gcc/varasm.c:1706 #4 0x00503118 in rest_of_decl_compilation (decl=0x4469dcc0, top_level=6317412, at_end=12999080) at /vol/gnu/src/gcc/gcc-dist/gcc/passes.c:235 #5 0x00507bfc in expand_one_var (var=0x4469dcc0, toplevel=100 'd') at /vol/gnu/src/gcc/gcc-dist/gcc/cfgexpand.c:559 #6 0x005094ac in tree_expand_cfg () at /vol/gnu/src/gcc/gcc-dist/gcc/cfgexpand.c:791 #7 0x0024896c in execute_pass_list (pass=0x44698210) at /vol/gnu/src/gcc/gcc-dist/gcc/tree-optimize.c:511 #8 0x00248ca8 in tree_rest_of_compilation (fndecl=0x0) at /vol/gnu/src/gcc/gcc-dist/gcc/tree-optimize.c:643 #9 0x005330bc in cgraph_expand_function (node=0x44699880) at /vol/gnu/src/gcc/gcc-dist/gcc/cgraphunit.c:822 #10 0x0053407c in cgraph_optimize () at /vol/gnu/src/gcc/gcc-dist/gcc/cgraphunit.c:1689 #11 0x004d6528 in toplev_main (argc=12717220, argv=0xc265b4) at /vol/gnu/src/gcc/gcc-dist/gcc/toplev.c:985 #12 0x00002584 in _start (argc=16, argv=0xbffff93c, envp=0xbffff980) at /SourceCache/Csu/Csu-47/crt.c:267 #13 0x8fe1a558 in __dyld__dyld_start () The file compiles without problems at -O0.

Created attachment 7569 [details] patch which moves darwin-fallback.o to the correct static library Using your hint for -lgcc -lgcc_eh -lgcc, well the patch which would do that not be the correct fix but I figured out what was going on. Oh, by the way the ICE you got is not known yet, please file it seperately.

Fine. I said the change above was a hack, and I wasn't sure whether it is the correct solution. > Oh, by the way the ICE you got is not known yet, please file it seperately. Ok, will do. Rainer
