* Recommit the fix for rdar://9289512 with a couple tweaks toChris Lattner2011-04-224-18/+113
| | | | | | | | | | | | | fix bugs exposed by the gcc dejagnu testsuite: 1. The load may actually be used by a dead instruction, which would cause an assert. 2. The load may not be used by the current chain of instructions, and we could move it past a side-effecting instruction. Change how we process uses to define the problem away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130018 91177308-0d34-0410-b5e6-96231b3b80d8

* DAGCombine: fold "(zext x) == C" into "x == (trunc C)" if the trunc is lossless.Benjamin Kramer2011-04-223-30/+73
| | | | | | | | | | | | On x86 this allows to fold a load into the cmp, greatly reducing register pressure. movzbl (%rdi), %eax cmpl $47, %eax -> cmpb $47, (%rdi) This shaves 8k off gcc.o on i386. I'll leave applying the patch in README.txt to Chris :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130005 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: Try to use a smaller encoding by transforming (X << C1) & C2 into (X & ↵Benjamin Kramer2011-04-222-0/+176
| | | | | | | | | | | | | | | | | | | | | | | (C2 >> C1)) & C1. (Part of PR5039) This tends to happen a lot with bitfield code generated by clang. A simple example for x86_64 is uint64_t foo(uint64_t x) { return (x&1) << 42; } which used to compile into bloated code: shlq $42, %rdi ## encoding: [0x48,0xc1,0xe7,0x2a] movabsq $4398046511104, %rax ## encoding: [0x48,0xb8,0x00,0x00,0x00,0x00,0x00,0x04,0x00,0x00] andq %rdi, %rax ## encoding: [0x48,0x21,0xf8] ret ## encoding: [0xc3] with this patch we can fold the immediate into the and: andq $1, %rdi ## encoding: [0x48,0x83,0xe7,0x01] movq %rdi, %rax ## encoding: [0x48,0x89,0xf8] shlq $42, %rax ## encoding: [0x48,0xc1,0xe0,0x2a] ret ## encoding: [0xc3] It's possible to save another byte by using 'andl' instead of 'andq' but I currently see no way of doing that without making this code even more complicated. See the TODOs in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129990 91177308-0d34-0410-b5e6-96231b3b80d8

* Branch folding is folding a landing pad into a regular BB.Bill Wendling2011-04-221-1/+1
| | | | | | | | | | | | | | | | An exception is thrown via a call to _cxa_throw, which we don't expect to return. Therefore, the "true" part of the invoke goes to a BB that has 'unreachable' as its only instruction. This is lowered into an empty MachineBB. The landing pad for this invoke, however, is directly after the "true" MBB. When the empty MBB is removed, the landing pad is directly below the BB with the invoke call. The unconditional branch is removed and then the two blocks are merged together. The testcase is too big for a regression test. <rdar://problem/9305728> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129965 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow allocatable ranges from global live range splitting to be split again.Jakob Stoklund Olesen2011-04-213-7/+45
| | | | | | | | | | | | | | | | | | | | | These intervals are allocatable immediately after splitting, but they may be evicted because of later splitting. This is rare, but when it happens they should be split again. The remainder intervals that cannot be allocated after splitting still move directly to spilling. SplitEditor::finish can optionally provide a mapping from new live intervals back to the original interval indexes returned by openIntv(). Each original interval index can map to multiple new intervals after connected components have been separated. Dead code elimination may also add existing intervals to the list. The reverse mapping allows the SplitEditor client to treat the new intervals differently depending on the split region they came from. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129925 91177308-0d34-0410-b5e6-96231b3b80d8
