I'm getting bootstrap failure with mainline on sparc-sun-solaris2.10 using cc for stage1. The failure occurs due to empty macro arguments. They occur in two places, one of which I've posted a patch for: http://gcc.gnu.org/ml/gcc-patches/2007-08/msg01131.html
The second occurance is in c-common.c on line 2249 where it says: C_COMMON_FIXED_TYPES (, fract); Other instances occur below that in the same file. In another thread, I fixed an empty macro argument problem encountered when using gcc-2.8.1 for stage1 here: http://gcc.gnu.org/ml/gcc-patches/2007-08/msg01119.html According to Joseph later in that thread, empty macro arguments are undefined in ISO C90. Since we claim to only require ISO C90 to bootstrap, and because we want to ensure older versions of GCC continue to be usable to bootstrap, IMHO we should not allow empty macro arguments in the sources. -- Summary: Bootstrap failure on solaris2 using cc due to empty macro arguments Product: gcc Version: 4.3.0 Status: UNCONFIRMED Keywords: build Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ghazi at gcc dot gnu dot org GCC host triplet: sparc-sun-solaris2.10 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33304
