gcov: Add __gcov_info_to_gdca()
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.

gcov: Add __gcov_info_to_gdca()
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]);

}
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.

gcov: Add __gcov_info_to_gdca()
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]);
}

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.

gcov: Add __gcov_info_to_gdca()
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;

}
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.

gcov: Add __gcov_info_to_gdca()
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.
