There was no problem with the preceding snapshots. I've still not tested under other platforms. % cat stc.c // gcc -O -finline-small-functions -finline-functions -fipa-pta -fpartial-inlining -c stc.c #include <assert.h> void zz0(void); static int xx0; void zz0(void) { assert(xx0 == 0); return; }; void zz1(void) { zz0(); return; }; void zz2(void) { zz0(); return; }; % % gcc -v -O -finline-small-functions -finline-functions -fipa-pta -fpartial-inlining -c stc.c Using built-in specs.
