2013-03-13Set symbolizer path in the test environment.Evgeniy Stepanov
This is needed to get symbolized stack traces when running LLVM tests under (A|M)San. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176933 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-13Refactor filename/directory in DICompileUnit into a DIFileDavid Blaikie

2013-03-12Update debug info test cases with empty SplitDebugFilename field.David Blaikie
This could be 'null' or the empty string, DIDescriptor::getStringField coalesces the two cases anyway so it's just a matter of legible/efficient representation. The change in behavior of the DICompileUnit::get* functions could be subsumed by the full verification check - but ideally that should just be an assertion if we could front-load the actual debug info metadata failure paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176907 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-12ARM cost model: Increase the cost for vector casts that use the stackArnold Schwaighofer
Increase the cost of v8/v16-i8 to v8/v16-i32 casts and truncates as the backend currently lowers those using stack accesses. This was responsible for a significant degradation on MultiSource/Benchmarks/Trimaran/enc-pc1/enc-pc1 where we vectorize one loop to a vector factor of 16. After this patch we select a vector factor of 4 which will generate reasonable code. unsigned char cle[32]; void test(short c) { unsigned short compte; for (compte = 0; compte <= 31; compte++) { cle[compte] = cle[compte] ^ c; } } radar://13220512 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176898 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-12Don't reserve R2 on Darwin/PPCHal Finkel
Now that only the register-scavenger version of the CR spilling code remains, we no longer need the Darwin R2 hack. Darwin can use R0 as a spare register in any case where the System V ABI uses it (R0 is special architecturally, and so is reserved under all common ABIs). A few test cases needed to be updated to reflect the register-allocation changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176868 91177308-0d34-0410-b5e6-96231b3b80d8

debug info format. These cases were found by further work to remove support for debug info versioning.

2013-03-08Disable statistics on Release builds and move tests that depend on -stats.Jan Wen Voung
Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.

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

2013-03-07Debug 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
