* Avoid int to string conversion in Twine or raw_ostream contexts.Benjamin Kramer2017-12-281-1/+1
| | | | | | Some output changes from uppercase hex to lowercase hex, no other functionality change intended. llvm-svn: 321526
* (Re-landing) Expose a TargetMachine::getTargetTransformInfo functionSanjoy Das2017-12-222-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-land r321234. It had to be reverted because it broke the shared library build. The shared library build broke because there was a missing LLVMBuild dependency from lib/Passes (which calls TargetMachine::getTargetIRAnalysis) to lib/Target. As far as I can tell, this problem was always there but was somehow masked before (perhaps because TargetMachine::getTargetIRAnalysis was a virtual function). Original commit message: This makes the TargetMachine interface a bit simpler. We still need the std::function in TargetIRAnalysis to avoid having to add a dependency from Analysis to Target. See discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-December/119749.html I avoided adding all of the backend owners to this review since the change is simple, but let me know if you feel differently about this.

* [WebAssembly] Disable tee_local optimizations when targeting the ELF ABI.Dan Gohman2017-12-201-1/+9
| | | | | | | These optimizations depend on the ExplicitLocals pass to lower TEE instructions, which is disabled in the ELF ABI, so disable them too. llvm-svn: 321131

* Rename LiveIntervalAnalysis.h to LiveIntervals.hMatthias Braun2017-12-136-7/+7
| | | | | | | | | | Headers/Implementation files should be named after the class they declare/define. Also eliminated an `#include "llvm/CodeGen/LiveIntervalAnalysis.h"` in favor of `class LiveIntarvals;` llvm-svn: 320546

* Revert "[WebAssemby] Support main functions with alternate signatures."Derek Schuff2017-12-081-45/+1
| | | | | | | | | This reverts commit 959e37e669b0c3cfad4cb9f1f7c9261ce9f5e9ae. That commit doesn't handle the case where main is declared rather than defined, in particular the even-more special case where main is a prototypeless declaration (which is of course the one actually used by musl currently). llvm-svn: 320121
* [WebAssemby] Support main functions with alternate signatures.Dan Gohman2017-12-071-1/+45
| | | | | | | | | | WebAssembly requires caller and callee signatures to match, so the usual C runtime trick of calling main and having it just work regardless of whether main is defined as '()' or '(int argc, char *argv[])' doesn't work. Extend the FixFunctionBitcasts pass to rewrite main to use the latter form. llvm-svn: 320041

* [WebAssembly] Fix fptoui lowering boundsDan Gohman2017-11-292-14/+47
| | | | | | | To fully avoid trapping on wasm, fptoui needs a second check to ensure that the operand isn't below the supported range. llvm-svn: 319354
* [WebAssembly] Support bitcasted function addresses with varargs.Dan Gohman2017-11-281-6/+5
| | | | | | | | | | | | | Generalize FixFunctionBitcasts to handle varargs functions. This in particular fixes the case where clang bitcasts away a varargs when calling a K&R-style function. This avoids interacting with tricky ABI details because it operates at the LLVM IR level before varargs ABI details are exposed. This fixes PR35385. llvm-svn: 319186
* [WebAssembly] Handle errors better in fast-isel.Dan Gohman2017-11-281-12/+40
| | | | | | | | | Fast-isel routines need to bail out in the case that fast-isel fails on the operands. This fixes https://bugs.llvm.org/show_bug.cgi?id=35064 llvm-svn: 319144
* [WebAssembly] Fix trapping behavior in fptosi/fptoui.Dan Gohman2017-11-288-19/+227
| | | | | | | | | | | | This adds code to protect WebAssembly's `trunc_s` family of opcodes from values outside their domain. Even though such conversions have full undefined behavior in C/C++, LLVM IR's `fptosi` and `fptoui` do not, and only return undef. This also implements the proposed non-trapping float-to-int conversion feature and uses that instead when available. llvm-svn: 319128
* Fix a bunch more layering of CodeGen headers that are in TargetDavid Blaikie2017-11-174-4/+4
| | | | | | | | All these headers already depend on CodeGen headers so moving them into CodeGen fixes the layering (since CodeGen depends on Target, not the other way around). llvm-svn: 318490

* [WebAssembly] Revise the strategy for inline asm.Dan Gohman2017-11-082-6/+25
| | | | | | | | | | | | | | | | | | | | | | Previously, an "r" constraint would mean the compiler provides a value on WebAssembly's operand stack. This was tricky to use properly, particularly since it isn't possible to declare a new local from within an inline asm string. With this patch, "r" provides the value in a WebAssembly local, and the local index is provided to the inline asm string. This requires inline asm to use get_local and set_local to read the register. This does potentially result in larger code size, however inline asm should hopefully be quite rare in WebAssembly. This also means that the "m" constraint can no longer be supported, as WebAssembly has nothing like a "memory operand" that includes an implicit get_local. This fixes PR34599 for the wasm32-unknown-unknown-wasm target (though not for the ELF target). llvm-svn: 317707
* Target/TargetInstrInfo.h -> CodeGen/TargetInstrInfo.h to match layeringDavid Blaikie2017-11-081-1/+1
| | | | | | | | This header includes CodeGen headers, and is not, itself, included by any Target headers, so move it into CodeGen to match the layering of its implementation. llvm-svn: 317647
* Move TargetFrameLowering.h to CodeGen where it's implementedDavid Blaikie2017-11-032-2/+2
| | | | | | | | | | | This header already includes a CodeGen header and is implemented in lib/CodeGen, so move the header there to match. This fixes a link error with modular codegeneration builds - where a header and its implementation are circularly dependent and so need to be in the same library, not split between two like this. llvm-svn: 317379

* TargetMachine: Merge TargetMachine and LLVMTargetMachineMatthias Braun2017-10-122-6/+5
| | | | | | | | | | | | | | | Merge LLVMTargetMachine into TargetMachine. - There is no in-tree target anymore that just implements TargetMachine but not LLVMTargetMachine. - It should still be possible to stub out all the various functions in case a target does not want to use lib/CodeGen - This simplifies the code and avoids methods ending up in the wrong interface.

| | | | | | | | | | | | | | | | | Summary: The pass to fix function bitcasts generates thunks for functions that are called directly with a mismatching signature. It was also generating thunks in cases where the function was address-taken, causing aliasing problems in otherwise valid cases. This patch tightens the restrictions for when the pass runs.

* Change encodeU/SLEB128 to pad to certain number of bytesSam Clegg2017-09-151-5/+2
| | | | | | | | | | | | | | | Previously the 'Padding' argument was the number of padding bytes to add. However most callers that use 'Padding' know how many overall bytes they need to write. With the previous code this would mean encoding the LEB once to find out how many bytes it would occupy and then using this to calulate the 'Padding' value.
