| | | | | | | | | | | | | | | | | | | | | | Mips shift instructions DSLL, DSRL and DSRA are transformed into DSLL32, DSRL32 and DSRA32 respectively if the shift amount is between 32 and 63 Here is a description of DSLL: Purpose: Doubleword Shift Left Logical Plus 32 To execute a left-shift of a doubleword by a fixed amount--32 to 63 bits Description: GPR[rd] <- GPR[rt] << (sa+32) The 64-bit doubleword contents of GPR rt are shifted left, inserting zeros into the emptied bits; the result is placed in GPR rd.

* Revert r160254 temporarily.Chandler Carruth2012-07-162-26/+28
| | | | | | | | | | | | It turns out that ASan relied on the at-the-end block insertion order to (purely by happenstance) disable some LLVM optimizations, which in turn start firing when the ordering is made more "normal". These optimizations in turn merge many of the instrumentation reporting calls which breaks the return address based error reporting in ASan. We're looking at several different options for fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160256 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | needs realignment. It is intended to fix PR11468. Old prologue and epilogue looked like this: push %rbp mov %rsp, %rbp and $alignment, %rsp push %r14 push %r15 ... pop %r15 pop %r14 mov %rbp, %rsp pop %rbp The problem was to reference the locations of callee-saved registers in exception handling: locations of callee-saved had to be re-calculated regarding the stack alignment operation. It would take some effort to implement this in LLVM, as currently MachineLocation can only have the form "Register + Offset". Funciton prologue and epilogue are now changed to: push %rbp mov %rsp, %rbp push %14 push %15 and $alignment, %rsp ... lea -$size_of_saved_registers(%rbp), %rsp pop %r15 pop %r14 pop %rbp Reviewed by Chad Rosier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160248 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply r160194, switching to use LV information for finding local kills.Chandler Carruth2012-07-151-56/+32
| | | | | | | | | | | | | | | | | | | | | The notable fix is to look at any dependencies attached to the kill instruction (or other instructions between MI nad the kill) where the dependencies are specific to the register in question. The old code implicitly handled this by rejecting the transform if *any* other uses were found within the block, but after the start point. The new code directly finds the kill, and has to re-use the existing dependency scan to check for non-kill uses. This was caught by self-host, but I found the bug via inspection and use of absurd assert scaffolding to compute the kills in two ways and compare them. So I have no useful testcase for this other than "bootstrap". I'd work harder to reduce a test case if this particular code were likely to live for a long time. Thanks to Benjamin Kramer for reviewing the fix itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160228 91177308-0d34-0410-b5e6-96231b3b80d8
