[v2,07/10] Test: Add testcases for form 5 of unsigned integer SAT_ADD simplify
Commit Message
From: Pan Li <pan2.li@intel.com>
The phiopt2 pass will also try the gimple_simplify for the form 5
of unsigned integer SAT_ADD. Thus add the testcase to make sure
it will be performed in phiopt2 pass.
gcc/testsuite/ChangeLog:
* gcc.dg/sat_arith_simplify.h: Add test helper macros.
* gcc.dg/sat_u_add-simplify-5-u16.c: New test.
* gcc.dg/sat_u_add-simplify-5-u32.c: New test.
* gcc.dg/sat_u_add-simplify-5-u64.c: New test.
* gcc.dg/sat_u_add-simplify-5-u8.c: New test.
