Enable mudflaps for Solaris _IF_ gcc is configured to use GNU's ld .
Here is the final result:
# make check
...
=== libmudflap Summary ===
# of expected passes 1131
# of unexpected failures 293
I am running i386-pc-solaris2.11 (OpenSolaris 2008.11) and configured the
trunk like this:
# /usr/local/bin/gcc -v
Using built-in specs.
Target: i386-pc-solaris2.11
Configured with: ../gcc_trunk/configure
--enable-languages=ada,c,c++,fortran,java,objc,obj-c++ --enable-shared
--disable-static --enable-decimal-float --enable-nls --without-system-libunwind
--with-gnu-as --with-as=/usr/local/bin/as --with-gnu-ld
--with-ld=/usr/local/bin/ld
Thread model: posix
gcc version 4.4.0 20090104 (experimental) (GCC)
# /usr/local/bin/ld -v
GNU ld (GNU Binutils) 2.19
# /usr/local/bin/as -v
GNU assembler version 2.19 (i386-pc-solaris2.11) using BFD version (GNU
Binutils) 2.19
I modified "gcc_build/i386-pc-solaris2.11/libmudflap/Makefile" to add
"-lsocket" to LIBS which allows most of the tests to work. This was not
necessary for any other testsuites, they worked as-is.
# LIBS = -ldl
LIBS = -ldl -lsocket
Some of the "unexpected failures" are simple compilation errors in the
tests which, when fixed, will likely become "expected passes". Example:
...
output is:
/usr/share/src/gcc_trunk/libmudflap/testsuite/libmudflap.c/pass47-frag.c:10:
warning: mudflap cannot track unknown size extern '__ctype'
_or_
Excess errors:
/usr/share/src/gcc_trunk/libmudflap/testsuite/libmudflap.c/pass-stratcliff.c:261:
error: invalid operands to binary - (have 'int' and 'char *')
/usr/share/src/gcc_trunk/libmudflap/testsuite/libmudflap.c/pass-stratcliff.c:281:
error: invalid operands to binary - (have 'int' and 'char *')
/usr/share/src/gcc_trunk/libmudflap/testsuite/libmudflap.c/pass-stratcliff.c:309:
warning: comparison between pointer and integer
...
A few of the "unexpected failures" are only in the "execution test" and
are the result of a Segmentation Fault. For the most part it is working.
The root configure script needs to be modified to allow mudflaps on this
platform _IF_ gcc is configured to use GNU ld (usually it does not) and
there needs a bit of fixing in the Makefile of libmudflap's testsuite.
Thanks,
Rob
