2013-03-08Add -verify-misched option.Andrew Trick
This verifies live intervals both before and after scheduling. It's useful for anyone hacking on live interval update. Note that we don't yet pass verification all the time. We don't yet handle updating nonallocatable live intervals perfectly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176685 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-08Revert r176154 in favor of a better approach.Bill Wendling
Code generation makes some basic assumptions about the IR it's been given. In particular, if there is only one 'invoke' in the function, then that invoke won't be going away. However, with the advent of the `llvm.donothing' intrinsic, those invokes may go away. If all of them go away, the landing pad no longer has any users. This confuses the back-end, which asserts. This happens with SjLj exceptions, because that's the model that modifies the IR based on there being invokes, etc. in the function. Remove any invokes of `llvm.donothing' during SjLj EH preparation. This will give us a CFG that the back-end won't be confused about. If all of the invokes in a function are removed, then the SjLj EH prepare pass won't insert the bogus code the relies upon the invokes being there. <rdar://problem/13228754&13316637> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176677 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-08Upgrade tests to the latest debug info format.David Blaikie
Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-07Rename isEarlierInSameTrace to isUsefulDominator.Jakob Stoklund Olesen
In very rare cases caused by irreducible control flow, the dominating block can have the same trace head without actually being part of the trace. As long as such a dominator still has valid instruction depths, it is OK to use it for computing instruction depths. Rename the function to avoid lying, and add a check that instruction depths are computed for the dominator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176668 91177308-0d34-0410-b5e6-96231b3b80d8

rdar:13370002 [pre-RA-sched] assertion: released too many times I tracked this down to an earlier hack that is no longer applicable and interfered with normal scheduler logic.

2013-03-07Debug Info: store the files and directories for each compile unit.Manman Ren
We now emit a line table for each compile unit. To reduce the prologue size of each line table, the files and directories used by each compile unit are stored in std::map<unsigned, std::vector< > > instead of std::vector< >. The prologue for a lto'ed image can be as big as 93K. Duplicating 93K for each compile unit causes a huge increase of debug info. With this patch, each prologue will only emit the files required by the compile unit. rdar://problem/13342023 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176605 91177308-0d34-0410-b5e6-96231b3b80d8

Fixes rdar:13349374. Volatile loads and stores need to be preserved even if the language standard says they are undefined.
