Currently gmp 5.0.2 fails to pass its make check when built with llvm-gcc.
This is a permutation of the problem we previously saw with clang which resulted
in the change of the "checking how to switch to read-only data section..." test
from...
const int foo = 123;
to..
extern const int foo; /* Suppresses C++'s suppression of foo */
const int foo = {1,2,3};
However this form of the test still results in the test incorrectly returning
.section __TEXT,__literal4,4byte_literals
using llvm-gcc and is the cause of the gmp testsuite failures. The fix
that has worked for me is to convert the test to...
static int foo = {1,2,3};
which works with both clang and llvm-gcc. I have attached a patch for this
change
for inclusion in the gmp5-5.0.2 package.
