2007-04-13Now that codegen prepare isn't defeating me, I can finally fix what I setChris Lattner
out to do! :) This fixes a problem where LSR would insert a bunch of code into each MBB that uses a particular subexpression (e.g. IV+base+C). The problem is that this code cannot be CSE'd back together if inserted into different blocks. This patch changes LSR to attempt to insert a single copy of this code and share it, allowing codegenprepare to duplicate the code if it can be sunk into various addressing modes. On CodeGen/ARM/lsr-code-insertion.ll, for example, this gives us code like: add r8, r0, r5 str r6, [r8, #+4] .. ble LBB1_4 @cond_next LBB1_3: @cond_true str r10, [r8, #+4] LBB1_4: @cond_next ... LBB1_5: @cond_true55 ldr r6, LCPI1_1 str r6, [r8, #+4] instead of: add r10, r0, r6 str r8, [r10, #+4] ... ble LBB1_4 @cond_next LBB1_3: @cond_true add r8, r0, r6 str r10, [r8, #+4] LBB1_4: @cond_next ... LBB1_5: @cond_true55 add r8, r0, r6 ldr r10, LCPI1_1 str r10, [r8, #+4] Besides being smaller and more efficient, this makes it immediately obvious that it is profitable to predicate LBB1_3 now :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35972 91177308-0d34-0410-b5e6-96231b3b80d8
2007-04-13Completely rewrite addressing-mode related sinking of code. In particular,Chris Lattner
this fixes problems where codegenprepare would sink expressions into load/stores that are not valid, and fixes cases where it would miss important valid ones. This fixes several serious codesize and perf issues, particularly on targets with complex addressing modes like arm and x86. For example, now we compile CodeGen/X86/isel-sink.ll to: _test: movl 8(%esp), %eax movl 4(%esp), %ecx cmpl $1233, %eax ja LBB1_2 #F LBB1_1: #T movl $4, (%ecx,%eax,4) movl $141, %eax ret LBB1_2: #F movl (%ecx,%eax,4), %eax ret instead of: _test: movl 8(%esp), %eax leal (,%eax,4), %ecx addl 4(%esp), %ecx cmpl $1233, %eax ja LBB1_2 #F LBB1_1: #T movl $4, (%ecx) movl $141, %eax ret LBB1_2: #F movl (%ecx), %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35970 91177308-0d34-0410-b5e6-96231b3b80d8
