Bug description:FFI:structure/union alignment [ext/ffi/tests/022.phpt] failure
Description:
------------
FFI:structure/union alignment [ext/ffi/tests/022.phpt] fails on Big
endian systems.
The TC fails in the following code block:
if (substr(PHP_OS, 0, 3) != 'WIN') {
test_size(32, "struct {char a; uint32_t b
__attribute__((aligned));}");
test_align(16, "struct {char a; uint32_t b
__attribute__((aligned));}");
}
The __attribute__((aligned(__BIGGEST_ALIGNMENT__))) returns 8 bytes on
s390x, whereas its 16 bytes on x86 architecture.
Hence the test functions output observed on s390x is :
test_size expects the size returned to be 16.
test_align expects the alignment returned to be 8.
Added a patch with TC changes specific to s390x. Kindly let me know if I
shall raise a PR with this changes.
Also Could you please ensure if additional source code changes are
needed?
