theraven	86d5f028a4	Don't remove ivar offset variables, even if we aren't using them.	14 years ago
theraven	8cf5e0412f	Update optimisation to work with LLVM trunk, remove the Makefile and use CMake for building the passes (out of tree builds are now easier).	14 years ago
theraven	abff244ef9	Started 1.6.1 release announcement, updated LLVM optimisations to work with LLVM 3.1.	14 years ago
buzzdee	5aec1ee728	Allow to build the optimizations for llvm with cmake. OK loong time ago from David.	14 years ago
theraven	02fe58d85a	Fix use-after-free in speculative inlining pass.	14 years ago
theraven	469ce7521c	Add missing file.	14 years ago
theraven	f2caea7f28	It turns out that allocating one word on stack every loop iteration doesn't scale very well. It also turns out that if you test the cache every loop iteration but never write to it that this doesn't really make things any faster...	14 years ago
theraven	d99a8b19ed	Remove debugging statements.	14 years ago
theraven	286892936d	Teach the optimisations to work in the presence of exception handling and if the front end emits objc_msgSend() instead of indirect lookups. The GNUstep-base test suite now passes when compiled with: -fno-objc-legacy-dispatch -Xclang -load -Xclang /path/to/libGNUObjCRuntime.so -O3	14 years ago
theraven	705135bb89	Some fixes to the Objective-C optimisation passes. Tested by compiling GNUstep base with clang at -O3 + all of the optimisations that this library enables at O3 and then running the test suite - results, looking good. Still to do before the release: turn objc_msgSend() into objc_msg_lookup_sender() and insert caching when not optimising for size.	14 years ago
theraven	ee3961f38e	Register LLVM passes with the new API.	15 years ago
theraven	b68a5dda6d	Get the libobjc2 optimisations building again with LLVM trunk.	15 years ago
theraven	81131acfbc	Fix LLVM trunk compatibility.	15 years ago
theraven	4f31ed8acd	Some tweaks to optimisation order.	15 years ago
theraven	2912bae0a7	Ooops, another debugging line left in which caused a pass not to run...	15 years ago
theraven	b7986e9efa	Ooops. Accidentally left the bit that actually did the optimisation commented out.	15 years ago
theraven	8f423d0e29	Fix non-fragile ivar short-circuiting (i.e. hard-code the CORRECT ivar addresses, don't make foo and foobar have the same offset).	15 years ago
theraven	5705845e98	Fixed some bugs with the optimisation passes and introduced support for automatically running them (requires LLVM 3 + a patch that is not yet in trunk, but should be soon).	15 years ago
theraven	34aa9f9455	Allowed LLVM optimisations to build against both LLVM 2.9 and LLVM 3.0.	15 years ago
theraven	15ddbdfd71	Added meta-pass that runs all of the LLVM optimisations.	15 years ago
theraven	9d5452b147	Fixed LLVM passes to compile with recent LLVM. Made class caching pass cache classes in a static variable if the original class is not available.	15 years ago
theraven	0c8d2bd7b8	Added missing files.	16 years ago
theraven	a6b5cd15dc	Rename the library with the lib prefix so it can actually be linked sensibly.	16 years ago
theraven	23447feca5	Profile-driven inlining of Objective-C methods.	16 years ago
theraven	9ea9a6cf41	Made inlining conditional on inlining actually being sensible.	16 years ago
theraven	6a58d3d49d	Added unfinished inliner that uses type feedback info to inline instance methods. Made class method inliner also inline message sends to super. Various updates caused by clang now attaching more sensible metadata to the IR.	16 years ago
theraven	c425b1bfdc	Initial (working) type feedback pass. Records the IMP for every message lookup. Note: This writes 3 words for every single message send, which means that it makes code VERY slow and can fill up the filesystem if you leave it enabled. The aim of this pass is to identify message send sites which can benefit from speculative inlining and inline caching. By itself, this pass is useless. It will later be combined with one that parses this information and then uses the existing caching and inlining infrastructure to optimize hot message send sites. Now, however, it's time for me to go and dance, so the useful bit will have to wait.	16 years ago
theraven	6cac2816cc	Added speculative inlining of class messages. Currently inlines all that it can, without deciding whether it's sensible.	16 years ago
theraven	beb8356367	Made ClassIMPCache a ModulePass (it shouldn't be a FunctionPass because it adds globals).	16 years ago
theraven	60f87bc4ad	Removed debugging code that shouldn't have been in last commit. Aside: Testing the two passes from the last commit shows that they provide about a factor of 10 speedup for class messages.	16 years ago
theraven	84b41a8464	Added -gnu-class-lookup-cache and -gnu-class-imp-cache passes. These add caching for class messages and also skip the class lookup (using the class symbol directly) where possible. In combination, these make class messages marginally slower than function calls, rather than significantly slower than message sends.	16 years ago
theraven	352dfe2d93	Removed some unneeded #includes.	16 years ago
theraven	874ec4bd66	Fixed IMP cacher to not cache the slot if the lookup function changes the receiver (this could result in a method being called on the wrong receiver, which would just be confusing).	16 years ago
theraven	dfc4a0286b	Factored out code that performs IMP caching into a separate class. This can now be used by other passes that cache IMPs outside of loops (for example, always caching class messages because they always have the same receiver).	16 years ago
theraven	1918888ce1	Added LoopIMPCachePass. This pass automatically performs IMP caching on all loops. Microbenchmark that just sends a message that does nothing 1000000000 times in a loop goes from taking 10.2 seconds to taking 4.7 after running the pass.	16 years ago
theraven	93251416eb	Added LLVM optimisation passes for libobjc2.	16 years ago
