Subject: [Bug bootstrap/39929] [4.5 Regression] Bootstrapping fails at stage 1 on powerpc-apple-darwin9 and powerpc-ibm-aix
Date: Mon, 27 Apr 2009 13:54:00 -0000 [thread overview]
Message-ID: <20090427135424.20884.qmail@sourceware.org> (raw)

------- Comment #2 from dje at gcc dot gnu dot org 2009-04-27 13:54 -------
This also fails on AIX. On AIX, the error appears as a failure while compiling
libobjc/linking.m.
A function in cgraphunit.c is being mis-compiled, possibly build_cdtor(). This
causes cgraph_build_static_cdtor() to be called with an invalid priority of
"-1", instead of 65535. The priority should not be negative. This negative
priority value generates an invalid global file function name:
_GLOBAL__I_-00001_0___objc_linking
A function name should not contain a minus sign, which is a syntax error.
Recompiling cgarphunit.c without optimization fixes the miscompilation. An
incorrect priority is calculated from decl_fini_priority_lookup(), but
recompiling tree.c does not change the failure.
