Chris Lattner	0078d9c5bb	Okay totally give up on trying to optimize aggregates that cannot be completely broken up into their elements. Too many programs break because of this. llvm-svn: 6440	2003-05-30 19:22:14 +00:00
Chris Lattner	d847be0539	add a check that allows the SRoA pass to avoid breaking programs, even if their behavior is technically undefined llvm-svn: 6438	2003-05-30 18:09:57 +00:00
Tanya Lattner	71e56e278c	Added the CloneTrace function which clones traces. It takes a vector of basic blocks, removes internal phi nodes, and returns a new vector of basic blocks. llvm-svn: 6431	2003-05-30 15:50:18 +00:00

Chris Lattner	ad44cd840b	* Revert to old behavior of ignoring a module if it doesn't contain a main function and no symbols were explicitly marked to be externalized. * Add new -internalize-public-api-list option that can be used if the symbol list is small, and making a new file is annoying. llvm-svn: 6289	2003-05-22 19:48:00 +00:00

Chris Lattner	9023155621	Initial checkin of PRE on LLVM. This implementation is still lacking in several ways: * Load expressions are not PRE'd well. Alias Analysis should be used to get accurate information when computing anticipatibility. * The expression collection implementation does not handle PHI nodes properly, thus the implementation misses many opportunities to PRE. * This code could be sped up quite a bit Despite these flaws, the code seems to work well, and handles PR's as one would expect. llvm-svn: 5759	2003-03-31 19:55:43 +00:00

Chris Lattner	28d103548d	Fix: ConstantMerge/2002-09-23-CPR-Update.ll Basically, this bug boiled down to calling replaceUsesOfWith on a constant, which changed it's shape in an illegal way.

Also the name is accurate * Add new isMaxValue, isMinValue, isMaxValueMinusOne, isMinValuePlusOne functions: This should be moved to Constant* classes eventually * Implement xor X, ALLONES -> not X * Fold ALL setcc's of booleans away * Handle various SetCC's for integers against values at the end of their ranges, possibly off by one.

Chris Lattner	c8e665431b	* Rename MethodPass class to FunctionPass - Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well llvm-svn: 2333	2002-04-27 06:56:12 +00:00

Chris Lattner	28a01b2069	* Clean up the code a bit * Allow structs with negative offsets. This enables the em3d benchmark to be made typesafe. In this case, the struct had an array as the first element, so a negative index was ok (the expr was -8 + 8x) llvm-svn: 2271	2002-04-16 22:10:36 +00:00

Chris Lattner	8f796d6310	* Add names to the symbol table for pool types and modified types * Handle more complex structure so that power works almost * Fix bug with pooldestroy call where we passed in the size of the object instead of the pool to destroy. bisort is now pool allocated successfully! llvm-svn: 2238	2002-04-13 19:25:57 +00:00
Chris Lattner	441e16f735	Implement function rewriting to use offsets instead of pointers in programs. This now works with treeadd at least, and perhaps other programs as well. llvm-svn: 2233	2002-04-12 20:23:15 +00:00
Chris Lattner	011ab80ed6	* Add documentation * Split the CleanGCC pass into two passes, a global pass and an IP pass.

This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P llvm-svn: 1288	2001-11-13 05:01:36 +00:00
Chris Lattner	4f8e9468cb	Avoid assertion failure when taking size of unsized array. Todo item herE llvm-svn: 1286	2001-11-13 04:59:41 +00:00

Chris Lattner	0043cc1109	Remove false optimization that basically broke everything llvm-svn: 1219	2001-11-09 01:08:10 +00:00
Chris Lattner	54e9f453c9	* Add better caching of data to avoid silly recusions * Only check to see if uses of instructions can be converted for expressions... so we don't look at all of the uses of a constant. This was making the code unnecessarily conservative llvm-svn: 1218	2001-11-08 22:06:31 +00:00
Chris Lattner	583e95e0b2	Improve raising significantly llvm-svn: 1214	2001-11-08 20:19:56 +00:00

Chris Lattner	7e89a616e6	Don't print spurious linking warnings about methods that are never used. Cleanup ExprTypeConvert a bit. llvm-svn: 1141	2001-11-05 19:43:10 +00:00
Chris Lattner	0ecba60d26	Use the expression map correctly. llvm-svn: 1140	2001-11-05 18:30:53 +00:00

Chris Lattner	36c5a79153	* Disable debug output * fix minor bug with taking datasize of unsized array type * Insert code to support speculative changes later llvm-svn: 1122	2001-11-04 21:32:11 +00:00
Chris Lattner	40a2d9076b	Convert backward conversion of expression trees into a new more powerful bidirectional approach. Add transforms for more instructions. llvm-svn: 1121	2001-11-04 20:21:12 +00:00
Chris Lattner	33d9cb9903	Minor method rename llvm-svn: 1119	2001-11-04 08:08:34 +00:00
Chris Lattner	f00563d39d	Add transformations for Load and GetElementPtr. Fix broken transform with shr. llvm-svn: 1118	2001-11-04 07:42:17 +00:00
Chris Lattner	eb7b620d58	Fix cast instructions that end up in bad places in GCC output llvm-svn: 1117	2001-11-04 07:40:51 +00:00
Chris Lattner	033324fc0c	Avoid making a broken transformation! llvm-svn: 1115	2001-11-03 21:30:22 +00:00
Chris Lattner	ec83fc091e	Add new cleanup pass: // 1. PHI nodes with multiple entries for the same predecessor. GCC sometimes // generates code that looks like this: // // bb7: br bool %cond1004, label %bb8, label %bb8 // bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ] // // which is completely illegal LLVM code. To compensate for this, we insert // an extra basic block, and convert the code to look like this: // // bb7: br bool %cond1004, label %bbX, label %bb8 // bbX: br label bb8 // bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ] // llvm-svn: 1114	2001-11-03 21:08:59 +00:00
Chris Lattner	784c623efb	* Export method to merge identically named methods * Add code to fix PHI nodes that are missing arguments. These PHI nodes can be generated by GCC if there is an uninitialized variable flowing into a merge point. For example: int foo(int y) { int X; if (y) X = 1; return X; } llvm-svn: 1110	2001-11-03 19:51:56 +00:00
Ruchira Sasanka	629a15247a	Commented out code so that copies are inserted for all phi args CahedCopyMap was disabled to insert phi elimination code for all phi args llvm-svn: 1105	2001-11-03 17:09:59 +00:00
Chris Lattner	629d7a7849	Changes to compile the TSP benchmark successfully. Favor warning instead of assertion failures. llvm-svn: 1103	2001-11-03 10:04:22 +00:00
Chris Lattner	1f3947c1d1	Add code to link method together with the same name if one is vararg and the other isn't. This resolves definitions like this: %list * "foo"(...) %list * "foo"(int) together which can often occur because C programmers don't put prototypes in like they should. GRR llvm-svn: 1102	2001-11-03 09:19:00 +00:00
Chris Lattner	3855f2c806	Don't forget to link type names together too. Fix for Olden/mst benchmark llvm-svn: 1094	2001-11-03 05:18:24 +00:00
Chris Lattner	1e60d6b762	Add extra code for debugging linker problems llvm-svn: 1091	2001-11-03 03:27:29 +00:00
Chris Lattner	9bc6b190cc	* Add comments for peepholes * Implement new peephole: // Peephole optimize the following instructions: // %t1 = cast {<...>} * %StructPtr to <ty> * // // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...> // %t1 = cast <eltype> * %t1 to <ty> * This peephole eliminated 9 evil casts in the health benchmark, and completely turned the addList method around. :) llvm-svn: 1085	2001-11-01 17:05:27 +00:00
Chris Lattner	71c842cddf	Add DCE as integral part of the level raising to avoid processing instructions that are dead llvm-svn: 1084	2001-11-01 07:00:51 +00:00
Chris Lattner	7567f6c15f	Expose the low level DCE mechanism to external users Refactor code to support it llvm-svn: 1083	2001-11-01 07:00:27 +00:00
Chris Lattner	9a13ececd8	* Implement expression type conversion for constant values * Fix a problem setting a name on a constant value that died because no symbol table was passed in * Add some comments describing the passes * Implement a new peephole: // Peephole optimize the following instructions: // %t = cast <T1>* %P to <T2> * ;; If T1 is losslessly convertable to T2 // store <T2> %V, <T2>* %t // // Into: // %t = cast <T2> %V to <T1> // store <T1> %t2, <T1>* %P llvm-svn: 1080	2001-11-01 05:57:59 +00:00
