Make it possible to test the generated assembly
This test framework feature is inspired by a similar feature in LLVM.
The programmer writes a bit of Cmm
#include "Cmm.h"
// Large memcpy's should lower to calls.
callMemcpy
{
W_ dst, src;
prim %memcpy(dst "ptr", src "ptr", 1024, 4) [];
}
and asserts what the generated assembly should look like, modulo
register naming.
callMemcpy:
movq ; Move arguments into place
movq
movl
movl
call memcpy
Patch edited and updated by Simon Marlow, and I also added a test for
unrolling memcpy and a simple constant-propagation test.
