2016-08-03	Adding -verify-machineinstrs option to PowerPC tests	Ehsan Amiri
	Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@277624 91177308-0d34-0410-b5e6-96231b3b80d8
2015-01-13	Use the integrated assembler as default on PowerPC	Ulrich Weigand
	This was already done in clang, this commit now uses the integrated assembler as default when using LLVM tools directly. A number of test cases using inline asm had to be adapted, either by updating the expected output, or by using -no-integrated-as (for such tests that deliberately use an invalid instruction in inline asm). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225819 91177308-0d34-0410-b5e6-96231b3b80d8
2014-12-03	[PowerPC] Print all inline-asm consts as signed numbers	Hal Finkel
	Almost all immediates in PowerPC assembly (both 32-bit and 64-bit) are signed numbers, and it is important that we print them as such. To make sure that happens, we change PPCTargetLowering::LowerAsmOperandForConstraint so that it does all intermediate checks on a signed-extended int64_t value, and then creates the resulting target constant using MVT::i64. This will ensure that all negative values are printed as negative values (mirroring what is done in other backends to achieve the same sign-extension effect). This came up in the context of inline assembly like this: "add%I2 %0,%0,%2", ..., "Ir"(-1ll) where we used to print: addi 3,3,4294967295 and gcc would print: addi 3,3,-1 and gas accepts both forms, but our builtin assembler (correctly) does not. Now we print -1 like gcc does. While here, I replaced a bunch of custom integer checks with isInt<16> and friends from MathExtras.h. Thanks to Paul Hargrove for the bug report. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223220 91177308-0d34-0410-b5e6-96231b3b80d8
