Age	Commit message (Collapse)	Author
2014-03-28	expand constantExprs for all illegal values, not just >=64bit, so that ↵	Alon Zakai
	things like nested i24 CEs are fixed up by promoteIntegers
2014-03-07	fix the case where exceptions are lowered and we already had ↵	Alon Zakai
	getHigh/preInvoke/postInvoke defined in the module
2014-03-06	Implement integer promotion for urem, udiv, srem, and sdiv	Dan Gohman
	The optimizer sometimes thinks it's beneficial to truncate all manner of i64 operators to narrower types, even when still wider than the platform's widest legal type.
2014-03-06	Fix a use-after-free error in GlobalOpt CleanupConstantGlobalUsers	Dan Gohman
	This is a backport of r197178 from LLVM trunk.
2014-03-05	Disable the ResolveAliases and GlobalCleanup passes.	Dan Gohman
	Also add a test for handling of global aliases.
2014-03-05	Disable the LowerExpectIntrinsic pass.	Dan Gohman

2014-03-05	Don't run a pass to strip dead prototypes; just ignore them.	Dan Gohman
	Also, fix the code for supressing declarations for no-op intrinsics.
2014-03-05	Clean up the handling of inline asm.	Dan Gohman
	Make inline asm a report_fatal_error instead of an assertion failure so that it's a little friendlier, and add a test to make sure llc -march=js rejects inline asm. Also disable the PNaCl inline asm("":::"memory") lowering pass. If people are using this, it's best that we diagnose it as it likely isn't portable. There are usually better alternatives.
2014-03-03	Fix alignment of vararg buffer allocas.	Dan Gohman
	Since we do 8-byte loads for va_arg of double, make sure the vararg buffer alloca is 8-byte aligned.
2014-02-28	Use range metadata instead of introducing selects.	Dan Gohman
	When GlobalOpt has determined that a GlobalVariable only ever has two values, it would convert the GlobalVariable to a boolean, and introduce SelectInsts at every load, to choose between the two possible values. These SelectInsts introduce overhead and other unpleasantness. This patch makes GlobalOpt just add range metadata to loads from such GlobalVariables instead. This enables the same main optimization (as seen in test/Transforms/GlobalOpt/integer-bool.ll), without introducing selects. The main downside is that it doesn't get the memory savings of shrinking such GlobalVariables, but this is expected to be negligible.

2014-02-28	Use more LLVM-idiomatic error reporting.	Dan Gohman

2014-02-28	Implement llvm.flt.rounds and disable the createRewriteLLVMIntrinsicsPass pass.	Dan Gohman

2014-02-26	NoExitRuntime	Alon Zakai

2014-02-25	Disable the RewritePNaClLibraryCalls pass, which isn't needed for Emscripten.	Dan Gohman

2014-02-25	Re-introduce ConstantExpr expansion for constants containing illegal types.	Dan Gohman

2014-02-25	Support GEP and ConstantExprs directly in the JSBackend.	Dan Gohman
	This patch also lays the groundwork for the single-use instruction trick to reduce the number of temporary variables.
2014-02-25	workaround for nativeclient issue 3798, wrong alignment on copy of a byval ↵	Alon Zakai

2014-02-13	Merge pull request #13 from sunfishcode/incoming	Alon Zakai
	Emscripten doesn't need to legalize pointers.
2014-02-13	don't do 32-bit shifts on 32-bit values, as it is undefined behavior	Alon Zakai

2014-02-13	Emscripten doesn't need to legalize pointers.	Dan Gohman

2014-02-13	handle ashr on >64 bits	Alon Zakai

2014-02-13	Don't leave behind unreachable blocks with illegal instructions.	Dan Gohman

2014-02-12	Revamp ExpandI64.	Dan Gohman
	By using a reverse-postorder traversal of the basic blocks, we can perform this transform in a single pass. This eliminates the need for tricky coordination between the passes.
