Bootstrap failures on solaris

Bootstrap failures on solaris

[Art Haas]

Hi.

I've had no luck with recent bootstraps on both i386-pc-solaris2.10 and
sparc-sun-solaris2.10. The error messages below are from builds performed
after updating my repo this morning.

i386-pc-solaris:

cc1: warnings being treated as errors

sparc-sun-solaris2.10:

Anyone else seeing failures like this?

I get this error on ppc also.

Hi.

Now that this patch has been commited, the build on i386-pc-solaris2.10
succeeds when building tree-ssa-loop-prefetch.o file but fails later on:

cc1: warnings being treated as errors
/export/home/arth/gnu/gcc.git/gcc/gcc.c: In function 'compare_files':
/export/home/arth/gnu/gcc.git/gcc/gcc.c:6635:2: error: request for
implicit conversion from 'void *' to 'caddr_t' not permitted in C++
make[3]: *** [gcc.o] Error 1
make[3]: *** Waiting for unfinished jobs....

The error is in an munmap() call, and a look at the <sys/mman.h> header
shows that the funcation arguments can be either 'void *' or 'caddr_t *'
depending on preprocessor values.

I believe that POSIX specifices that munmap takes a void * argument.  Is
there some preprocessor define we can use to direct the Solaris header
files to compile in POSIX mode?  If so, it should work to add it to
CFLAGS (using +=) in TOPLEVEL/config/mh-solaris.

I tripped up on the same issue a while ago, this should work:

-D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED=1

See http://www.kayari.org/doc/c++/suncc.html for other options.

Every other call to munmap in gcc/ is given a char* or has a cast to
caddr_t.

This patch should fix it.  I'll check it in shortly.

The above should be easy to fix using HOST_WIDE_INT_PRINT_DEC instead of
"%ld".  You'll have to pry apart the format string and insert the macro
via compile-time string contatenation.  See other uses for examples.
