9618bca Restructure code to reduce ifcvt compile time cost. by Evan Cheng · 18 years ago
a9bf49c Fix the build. by Reid Spencer · 18 years ago
1c9f91d Don't change CFG during analysis stage. Do so during ifcvt and invalidate predecessors accordingly. by Evan Cheng · 18 years ago
7e75ba8 Carefully remove extraneous CFG edges after each ifcvt. by Evan Cheng · 18 years ago
2acdbcc Correct transfer predicate information. by Evan Cheng · 18 years ago
edf4896 Hidden options to help debugging ifcvt issues. by Evan Cheng · 18 years ago
ac5f142 Allow more cmp / bcc to be predicated; clean up triangle ifcvt checking code. by Evan Cheng · 18 years ago
27af5c4 Only remove the edge from entry to false if false block is merged. by Evan Cheng · 18 years ago
f476961 ifcvt a triangle: don't merge ifcvt block with rejoin block if it can fall through to it. If merged, the resulting block is not a candidate for iterative ifcvting since it contains both predicated and non-predicated code. by Evan Cheng · 18 years ago
d4de6d9 Lots of bug fixes. Now finally in a reasonable state. by Evan Cheng · 18 years ago
96dd9a8 Quick patch to fix the build, based on what it appears Evan meant to write. by Owen Anderson · 18 years ago
7a65547 Lots of bug fixes. by Evan Cheng · 18 years ago
3d6f60e If a unconditional branch is added to branch to the false path during ifcvt, the predicated block cannot be iteratively ifcvted. by Evan Cheng · 18 years ago
cb78d67 Minor statistics counting bug. by Evan Cheng · 18 years ago
e705213 Fix a couple of typos and be smarter about order of blocks when ifcvt a diamond. by Evan Cheng · 18 years ago
993fc95 Fix diamond shape ifcvt bugs. by Evan Cheng · 18 years ago
a1a9f40 ReplaceUsesOfBlockWith() can modify the predecessors list. by Evan Cheng · 18 years ago
e004317 Do not ifcvt if either true / false path is a backedge. Not profitable in almost all cases. by Evan Cheng · 18 years ago
c53ef58 I had a senior moment. by Evan Cheng · 18 years ago
8ed680c If the predicated block requires an early exit, end the block there and add a unconditional branch to false block. AnalyzeBranch() does not understand early exits. by Evan Cheng · 18 years ago
f5305f9 Fix some subtle bugs: bug during succeessor copying; incorrectly updating states of ifcvted blocks. by Evan Cheng · 18 years ago
3ec4254 Forgot to check for if iterator reached the end. by Evan Cheng · 18 years ago
b6665f6 Let IfConverter loose. Allow more aggressive subsumptions; reorder basic blocks to expose more ifcvt opportunities; code clean up and fixes. by Evan Cheng · 18 years ago
b5a0690 Correctly mark early-exit on the false path. by Evan Cheng · 18 years ago
8c52938 Ifcvt triangle: don't ifcvt 'true' BB if it has other predecessors; don't merge 'false' BB if it has other predecessors. by Evan Cheng · 18 years ago
fe57a7e Remove a bogus check. Even terminators in a ifcvt need to be predicated. Unconditional branches can usually be converted to conditional ones. by Evan Cheng · 18 years ago
5f70218 Allow multiple ifcvt candidates to share children blocks; add some debugging code. by Evan Cheng · 18 years ago
f15d44c Fix a typo. by Evan Cheng · 18 years ago
8258210 Change traversal order to bottom up in preparation for more aggressive if-conversion. by Evan Cheng · 18 years ago
58fbb9f Don't merge in tail block of a diamond if it has more than one predecessors after if-conversion. by Evan Cheng · 18 years ago
c8ed9ba If there is an empty block between a source and its successor block, it still requires a unconditional branch. by Evan Cheng · 18 years ago
4bec8ae Silly boog. by Evan Cheng · 18 years ago
a13aa95 Preliminary iterative if-conversion support. by Evan Cheng · 18 years ago
a6b4f43 If-convert early exit blocks (returns, etc.); bug fixes, etc. by Evan Cheng · 18 years ago
7f8ff8a Clean up. by Evan Cheng · 18 years ago
36489bb Change to depth-first traversal. by Evan Cheng · 18 years ago
cf6cc11 Some restructuring in preparation for most aggressive if-conversion. by Evan Cheng · 18 years ago
6092ca1 Watch out for blocks that end with a return. by Evan Cheng · 18 years ago
47d2502 If true / false blocks fallthrough before ifcvt, add unconditional branches to ifcvt'd block. by Evan Cheng · 18 years ago
86cbfea Make use of target specific block size limits; bug fixes. by Evan Cheng · 18 years ago
d6ddc30 isBlockPredicable() always ignore terminal instructions; add comments. by Evan Cheng · 18 years ago
c3a289c Rename M_PREDICATED to M_PREDICABLE; Moved isPredicable() to MachineInstr. by Evan Cheng · 18 years ago
c5d05ef Devang points out that we need an assertion here. by Evan Cheng · 18 years ago
4e65485 Initial commit of (very basic) if converter. by Evan Cheng · 18 years ago
