Have you been able to track this with RTH? Do you care about this bug be fixed for 3.4.5? We're in 3.4.6 pre-release business now. -- Gaby -- gdr at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rth at gcc dot gnu dot org, | |gdr at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15231 ^ permalink raw reply [flat|nested] 6+ messages in thread

Compile the attached testcase with gcc -Os. The resulting assembly contains:
.align 2
.L24:
.word __icmp_inode+320
.word .L22
.word .L21
.word .LC3
but labels L22 and L23 are not defined anywhere.

Labels L22 and L21 were (when created) the addresses of objects in the code. However, they are deleted (presumably as unreachable), but the references to the lables persist. This is presumably exactly the case that RTH believed couldn't happen when he mentioned this in his email here: http://gcc.gnu.org/ml/gcc-patches/2000-05/msg00881.html and the reason we don't abort on ARM is that we never call output_constant_pool since we roll our own mini-pools. I've sofar been unsuccessful in reducing the testcase to something more managable. -- What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed|2005-02-22 04:10:35 |2005-09-02 22:27:33 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15231 ^ permalink raw reply [flat|nested] 6+ messages in thread
