* llvm-cov: Use uint32_t for loop variables to be more consistent.Bob Wilson2013-10-22
| | | | | | | | | The loop bounds here are uint32_t variables, so it makes sense for the loop variables to have the same type. Patch by Yuchen Wu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193192 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: fix a typo and rename a variable.Bob Wilson2013-10-22
| | | | | | | | | Rename Size to EndPos, which makes more sense because the variable stores the last location of the blocks. Patch by Yuchen Wu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193189 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix llvm-cov counts to be 64-bit integers to avoid overflows.Bob Wilson2013-10-22
| | | | | | | | | | Line counts in llvm-cov are read in as 64-bit integers but were being truncated to 32-bit in collectLineCounts(), which caused overflow for large counts. This patch fixes all counts to be uint64_t. Patch by Yuchen Wu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193172 91177308-0d34-0410-b5e6-96231b3b80d8

* Change llvm-cov output formatting to be more similar to gcov.Bob Wilson2013-10-22
| | | | | | | | | | | | - Replaced tabs with proper padding - print() takes two arguments, which are the GCNO and GCDA filenames - Files are listed at the top of output, appended by line 0 - Stripped strings of trailing \0s - Removed last two lines of whitespace in output Patch by Yuchen Wu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193148 91177308-0d34-0410-b5e6-96231b3b80d8
* Move the printing of llvm-cov information out from collectLineCounts().Bob Wilson2013-10-22
| | | | | | | | | | collectLineCounts() should only organize the output data. This is done in anticipation of subsequent changes which will pass in GCNO and GCDA filenames into the print function where it is printed similar to the gcov output.

| | | | | | | | | | | | The C API currently allows to dump values (LLVMDumpValue), but a similar method for types was not exported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | is updated to use DITypeRef. Move isUnsignedDIType and getOriginalTypeSize from DebugInfo.h to be static helper functions in DwarfCompileUnit. We already have a static helper function "isTypeSigned" in DwarfCompileUnit, and a pointer to DwarfDebug is added to resolve the derived-from field. All three functions need to go across link for derived-from fields, so we need to get hold of a type identifier map. A pointer to DwarfDebug is also added to DbgVariable in order to resolve the derived-from field. Debug info verifier is updated to check a derived-from field is a TypeRef. Verifier will not go across link for derived-from fields, in debug info finder, we go across the link to add derived-from fields to types. Function getDICompositeType is only used by dragonegg and since dragonegg does not generate identifier for types, we use an empty map to resolve the derived-from field. When printing a derived-from field, we use DITypeRef::getName to either return the type identifier or getName of the DIType.

| | | | | | | | Working on a better solution to this. This reverts commit 7d4e9934e7ca83094c5cf41346966c8350179ff2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190990 91177308-0d34-0410-b5e6-96231b3b80d8
* Encapsulate PassManager debug flags to avoid static init and cxa_exit.Andrew Trick2013-09-18
| | | | | | | | | | | | | | This puts all the global PassManager debugging flags, like -print-after-all and -time-passes, behind a managed static. This eliminates their static initializers and, more importantly, exit-time destructors. The only behavioral change I anticipate is that tools need to initialize the PassManager before parsing the command line in order to export these options, which makes sense. Tools that already initialize the standard passes (opt/llc) don't need to do anything new. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190974 91177308-0d34-0410-b5e6-96231b3b80d8

* MemCpyOptimizer: Use max legal int size instead of pointer sizeMatt Arsenault2013-09-16
| | | | | | | | | | | | If there are no legal integers, assume 1 byte. This makes more sense than using the pointer size as a guess for the maximum GPR width. It is conceivable to want to use some 64-bit pointers on a target where 64-bit integers aren't legal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190817 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | Definition of DIRef used to require the full definition of DIType because of usage of DIType::isType in DIRef::resolve. We now use DIDescriptor::isType instead to remove the requirement and move definition of DIRef before DIType. With this, we can move the definition of DIType::getContext to the header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190540 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | In DIBuilder, the context field of a TAG_member is updated to use the scope reference. Verifier is updated accordingly. DebugInfoFinder now needs to generate a type identifier map to have access to the actual scope. Same applies for BreakpointPrinter. processModule of DebugInfoFinder is called during initialization phase of the verifier to make sure the type identifier map is constructed early enough. We are now able to unique a simple class as demonstrated by the added testing case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190334 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: move DIScope::getContext to DwarfDebug.Manman Ren2013-09-09
| | | | | | | | | | | | | DIScope::getContext is a wrapper function that calls the specific getContext method on each subclass. When we switch DIType::getContext to return DIScopeRef instead of DIScope, DIScope::getContext can no longer return a DIScope without a type identifier map. DIScope::getContext is only used by DwarfDebug, so we move it to DwarfDebug to have easy access to the type identifier map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190330 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert patches to add case-range support for PR1255.Bob Wilson2013-09-09
| | | | | | | | | | | | | | | | | The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release.

* Debug Info: Rename DITypeRef to DIScopeRef.Manman Ren2013-09-09
| | | | | | | | | | | | | | | | | | | | | | | A reference to a scope is more general than a reference to a type since DIType is a subclass of DIScope. A reference to a type can be either an identifier for the type or the DIType itself, while a reference to a scope can be either an identifier for the type (when the scope is indeed a type) or the DIScope itself. A reference to a type and a reference to a scope will be resolved in the same way. The only difference is in the verifier when a field is a reference to a type (i.e. the containing type field of a DICompositeType) or a field is a reference to a scope (i.e. the context field of a DIType). This is to get ready for switching DIType::getContext to return DIScopeRef instead of DIScope. Tighten up isTypeRef and isScopeRef to make sure the identifier is not empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190322 91177308-0d34-0410-b5e6-96231b3b80d8
