From: Pan Li <pan2...@intel.com>
The phiopt2 pass will also try the gimple_simplify for the form 9
of unsigned integer SAT_ADD. Thus add the testcase to make sure
it will be performed in phiopt2 pass.
The below test suites are passed for this patch:
1. The rv64gcv fully regression tests.
2. The x86 bootstrap tests.
3. The x86 fully regression tests.
gcc/testsuite/ChangeLog:
* gcc.dg/sat_arith_simplify.h: Add test helper macros.
* gcc.dg/sat_u_add-simplify-9-u16.c: New test.
* gcc.dg/sat_u_add-simplify-9-u32.c: New test.
* gcc.dg/sat_u_add-simplify-9-u64.c: New test.
* gcc.dg/sat_u_add-simplify-9-u8.c: New test.
