In the C99 standard, floating constants are defined in section 6.4.4.2. A
floating constant of type double is unsuffixed; there is no 'd' or 'D' suffix.
Unless I'm missing something the test case is invalid

Rob, your various assertions do not show that there is a bug here. The failure
of gcc.target/i386/funcspec-3.c described in comment #41 does not prove that

In response to comment #34, the -B option overrides GCC_EXEC_PREFIX and the
compiler being tested in the build directory is invoked with -B.
GCC_EXEC_PREFIX will only be used to find files that are not in the build

I assume that the person who sent me the test did so because it passes with
some other implementation, but that doesn't mean it's widespread. It's fine

The code in question is in the 4.3 branch but not 4.2. The changes are very
minimal, so the patch is probably appropriate for the 4.3 branch. I had
already planned to ask to put it there as well as mainline

The tests listed in the submitter's description also fail (according to
archived testresults) on powerpc-unknown-linux-gnu, hppa-unknown-linux-gnu, and
powerpc-ibm-aix5.3.0.0.

The test passes with a simple build of gcc with the patch from comment#3. I
fired off a bootstrap and testsuite run.

This version of the small C testcase fails with current mainline

The new testcase passes with -O1 -funsafe-math-optimizations
-fno-tree-dominator-opts. The dom1 dump for -O1 -funsafe-math-optimizations
twice reports Invalid sum of incoming frequencies.

The operand of a postincrement and friends must be a modifiable lvalue. The
type check code for both C and C++ calls get_unwidened, which removes the cast
when it's a different size but leaves the cast when it's

Sigh. My nifty small C testcase doesn't fail with current mainline.

I tested with -m32 on powerpc64-linux, not with both -m32/-m64 which would have
caught this; I'll test with both for related patches.
The test previously used { dg-warning }, which matched any message from that
line

This is twisting my brain, but in this simplified testcase:
__PTRDIFF_TYPE__ p;
short q;
void foo () { ((char *)p)++; }
void bar () { ((char *)q)++; }
we get an error with both -m32 and-m64 for foo
--- Comment #4 from janis at gcc dot gnu dot org 2008-09-17 17:38 ---
The same thing happens in C for the simplified testcase; z.c is a copy of z.C
from comment #3:
elm3b149% /home/janis/tools/gcc-trunk-anonsvn/bin/gcc -c -m32 z.c
z.c: In function foo:
z.c:3: error: lvalue
