2019-02-18PR c++/89336 - multiple stores in constexpr stmt.Jason Merrill4-9/+115

2019-02-17[RS6000] Fix <bd>_<mode> and <bd>tf_<mode> splittersAlan Modra2-3/+10
This patch fixes a bug that can result in "insn does not satisfy its constraints" if these splitters fire due to not getting ctr for the jump insn. Since the jump insn can have any of r,m,d,wi,c,l as the decremented count output, it's not sufficient to check for gpc_reg_operand (which matches VSX regs for example). Seen after correcting register_move_cost when the cost of gpr <-> vsx is much lower. Since this is a prerequisite to fixing PR89271, I'm mentioning that PR in the ChangeLog. The <bd>tf_<mode> split had a further bug in that it wouldn't match if the count output was m,d,wi, or l. PR target/89271 * config/rs6000/rs6000.md (<bd>_<mode> split): Check for an int output reg on add insn. (<bd>tf_<mode> split): Likewise. Match predicates with insn. From-SVN: r268968

2019-02-16Fix excess warnings from -Wtype-limits with location wrappers (PR c++/88680)David Malcolm4-3/+77
PR c++/88680 reports excess warnings from -Wtype-limits after the C++ FE's use of location wrappers was extended in r267272 for cases such as: const unsigned n = 8; static_assert (n >= 0 && n % 2 == 0, ""); t.C:3:18: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] 3 | static_assert (n >= 0 && n % 2 == 0, ""); | ~~^~~~ The root cause is that the location wrapper around "n" breaks the suppression of the warning for the "if OP0 is a constant that is >= 0" case.

2019-02-15compiler,runtime: use __builtin_dwarf_cfa for getcallerspCherry Zhang7-21/+34
Currently, the compiler lowers runtime.getcallersp to __builtin_frame_address(1). In the C side of the runtime, getcallersp is defined as __builtin_frame_address(0). They don't match. Further, neither of them actually returns the caller's SP. On AMD64, __builtin_frame_address(0) just returns the frame pointer. __builtin_frame_address(1) returns the memory content where the frame pointer points to, which is typically the caller's frame pointer but can also be garbage if the frame pointer is not enabled. This CL changes it to use __builtin_dwarf_cfa(), which returns the caller's SP at the call site. This matches the SP we get from unwinding the stack. Currently getcallersp is not used for anything real. It will be used for precise stack scan (a new version of CL 159098).

There's a bit of a disconnect between the feature flags that don't test the fpu and ones that do when the test itself also forces an architecture. The forcing of the architecture would change the defaults and without explicitly giving the correct fpu again the test would fail. I don't see a good way to solve this problem, really the feature tests should ideally contain the extra options the test adds too, but for this specific case it can be solved by always testing the fpu explicitly.
