gcov_info::n_functions type is initialized by generated
code in build_info_type:
/* n_functions */
field = build_decl (BUILTINS_LOCATION, FIELD_DECL, NULL_TREE,
get_gcov_unsigned_t ());
It uses gcov_unsigned_t, but the struct definition in libgcov.h uses
unsigned type. That brings troubled on 16-bit targets.

Support merging of profiles that are built from a different .o files
but belong to the same source file. Moreover, a checksum is verified
during profile merging and so we can safely combine such profile.

If -fprofile-update=atomic is used, then the target must provide atomic
operations for the counters of the type returned by get_gcov_type().
This is a 64-bit type for targets which have a 64-bit long long type.
On 32-bit targets this could be an issue since they may not provide
64-bit atomic operations. Allow targets to override the default type
size with the new TARGET_GCOV_TYPE_SIZE target hook.
If a 32-bit gcov type size is used, then there is currently a warning in
libgcov-driver.c in a dead code block due to
sizeof (counter) == sizeof (gcov_unsigned_t):
libgcc/libgcov-driver.c: In function 'dump_counter':
libgcc/libgcov-driver.c:401:46: warning: right shift count >= width of type [-Wshift-count-overflow]

Add __gcov_info_to_gcda() to libgcov to get the gcda data for a gcda info in a
freestanding environment. It is intended to be used with the
-fprofile-info-section option. A crude test program which doesn't use a linker
script is (use "gcc -coverage -fprofile-info-section -lgcov test.c" to compile
it):
#include <gcov.h>
#include <stdio.h>
#include <stdlib.h>
extern const struct gcov_info *my_info;
static void
filename (const char *f, void *arg)
{
printf("filename: %s\n", f);
}
static void
dump (const void *d, unsigned n, void *arg)
{
const unsigned char *c = d;
for (unsigned i = 0; i < n; ++i)
printf ("%02x", c[i]);
}
static void *
allocate (unsigned length, void *arg)
{
return malloc (length);
}
int main()
{
__asm__ volatile (".set my_info, .LPBX2");
__gcov_info_to_gcda (my_info, filename, dump, allocate, NULL);
return 0;
}
With this patch, <stdint.h> is included in libgcov-driver.c even if
inhibit_libc is defined. This header file should be also available for
freestanding environments. If this is not the case, then we have to define
intptr_t somehow.
The patch removes one use of memset() which makes the <string.h> include
superfluous.

If you attempt a profiled bootstrap on the MinGW platforms with -jN, N > 1,
it miserably fails because of profile mismatches all over the place, the
reason being that gcov has no support for parallelism on these platforms.

As reported, bootstrap currently fails on older Darwin because MAP_ANONYMOUS

The patch fixes tree-prof.exp tests on solaris11 and i686-linux-gnu,
problem was that sizeof of a pointer is different from sizeof gcov_type.
I'm going to install it if there are no objections.
