Bug #: 50167
Summary: gmp memory functions are extern "C" (graphite)
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: [email protected]

Hello,
with gcc moving to C++, a few things need adapting. In particular, when asking
for the gmp memory functions, this:
void (*gmp_free) (void *, size_t);
mp_get_memory_functions (NULL, NULL, &gmp_free);
becomes wrong. One should have somewhere (protected by tests on __cplusplus
since we are still building with C compilers):
extern "C" {
typedef void (*mytype) (void *, size_t);
}
And then:
mytype gmp_free;
mp_get_memory_functions (NULL, NULL, &gmp_free);
g++ can't see the difference (yet? see Bug 2316), but some other compilers can
(sunpro), and we want other C++ compilers to be usable for stage1.
This code appears in 2 files:
./gcc/graphite-ppl.c
./gcc/graphite-interchange.c
