* [Assembler] Enable nicer diagnostics for inline assembly.Sanne Wouda2017-02-087-43/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed test. Summary: Enables source location in diagnostic messages from the backend. This is after parsing, during finalization. This requires the SourceMgr, the inline assembly string buffer, and DiagInfo to still be alive after EmitInlineAsm returns. This patch creates a single SourceMgr for inline assembly inside the AsmPrinter. MCContext gets a pointer to this SourceMgr. Using one SourceMgr per call to EmitInlineAsm would make it difficult for MCContext to figure out in which SourceMgr the SMLoc is located, while a single SourceMgr can figure it out if it has multiple buffers. The Str argument to EmitInlineAsm is copied into a buffer and owned by the inline asm SourceMgr. This ensures that DiagHandlers won't print garbage. (Clang emits a "note: instantiated into assembly here", which refers to this string.) The AsmParser gets destroyed before finalization, which means that the DiagHandlers the AsmParser installs into the SourceMgr will be stale. Restore the saved DiagHandlers. Since now we're using just one SourceMgr for multiple inline asm strings, we need to tell the AsmParser which buffer it needs to parse currently. Hand a buffer id -- returned from SourceMgr:: AddNewSourceBuffer -- to the AsmParser.

* Revert r294356, "DebugInfo: Track spilled variables in LiveDebugValues"NAKAMURA Takumi2017-02-082-605/+7
| | | | | | | | | | | | | | It caused undefined behavior in VarLoc. As far as I investigated, - VarLoc::VarLoc() treats negative offset value as InvalidKind. Consider the case that (int64_t)MI.getOperand(1).getImm() is negative and whether it satisfies ((uint64_t)Offset < (1ULL << 32)). - Comparison operators in VarLoc behave undefined since VarLoc::Loc.Hash is uninitialized in case of InvalidKind. I guess Offset (in VarLoc) could be made aware of signed, but I am not sure. So I have reverted it for now. llvm-svn: 294447

* [ARM] GlobalISel: Add FPR reg bankDiana Picus2017-02-087-2/+122
| | | | | | | | | | | | | Add a register bank for floating point values and select simple instructions using them (add, copies from GPR). This assumes that the hardware can cope with a single precision add (VADDS) instruction, so the legalizer will treat G_FADD as legal and the instruction selector will refuse to select if the hardware doesn't support it. In the future we'll want to be more careful about this, and legalize to libcalls if we have to use soft float. llvm-svn: 294442

* [AArch64][TableGen] Skip tied result operands for InstAliasAmara Emerson2017-02-0824-248/+253
| | | | | | | | | | | | | | | | | | | | | | | This patch checks the number of operands in the resulting instruction instead of just the alias, then skips over tied operands when generating the printing method. This allows us to generate the preferred assembly syntax for the AArch64 'ins' instruction, which should always be displayed as 'mov' according to the ARMARM. Several unit tests have changed as a result, but only to reflect the preferred disassembly. Some other InstAlias patterns (movk/bic/orr) needed a slight adjustment to stop them becoming the default and breaking other unit tests. Patch by Graham Hunter.

* CVP: Make CVP iterate in an order that maximizes reuse of LVI cacheDaniel Berlin2017-02-081-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: After the DFS order change for LVI, i have a few testcases that now take forever. The TL;DR - This is mainly due to the overdefined cache, but that requires predicateinfo to fix[1] In order to maximize reuse of the LVI cache for now, change the order we iterate in. This reduces my testcase from 5 minutes to 4 seconds. I have verified cases like gmic do not get slower. I am playing with whether the order should be postorder or idf. [1] In practice, overdefined anywhere should be overdefined everywhere, so this cache should be global. That also fixes this bug. The problem, however, is that LVI relies on this cache being filled in per-block because it wants different values in different blocks due to precisely the naming issue that predicateinfo fixes. With predicateinfo, making the cache global works fine on individual passes, and also resolves this issue.
