gcc reports the signedness probelm correctly, but g++ does not. See below for a
demonstration:

#include
using namespace std;
void foo (unsigned int a){
cout << a << endl;
}
int main(){
int b = -1;
foo (b);
return 0;
}

A consulting client of mine has asked me to make a cpp patch that
causes GCC to optionally expand preprocessor macros in #pragmas. He
is trying to migrate a huge codebase from Microsoft C to GCC. The
code has a lot of pragmas like

where FOO is a symbol created by a #define statem

The vect-reduc-dot-s16.c testcase fails because two loops were vectorized, and
we only expected one to be vectorized.
The problem here is that the loop in foo1 is not supposed to be recognized and
vectorized as a dot

Dorit's analysis of vect-reduc-pattern-2.c in comment #1 is correct. The loop
that sums char into int is not vectorized, because the widen_ssumv8qi3 pattern
has the wrong output mode (HI instead of SI). Dorit's sugg
gcc/gcc.c has a comment at the top that's a guide to adding a command line
option. It's incomplete: it should say to add the new option to c.opt and
rebuild the compiler, and then describe how the variable OPT_whatever gets
created by the awk scripts during the build process, so you can then check

I think this is more of a dup of bug 19180 which is the bug about lacking
documention about adding an option in general.

The problem here is ASM_OUTPUT_ASCII.
The testcase is a big file with a lot of functions that have long function
names. It is 4MB of C++ code, producing a 28MB .s file in about 15 seconds.

Reduced Testcase:
static int unit_cache[3];
void find_unit_1 (int n, int do_create)
{
int *p;
int c, created = 0;
if (p == 0)
if (do_create)
created = 1;
for (c = 0; c < 2; c++)
unit_cache[c] = unit_cache[c + 1];

Compile that testcase with -O2 and you will recieve an ICE.

I should say this was while building libgfortran/io/unit.c which makes this a

Autogen is only required for testing fixincludes which really is not required
for testing a patch except a fixincludes patch.
use "make -k check" instead of just
