Temporarily Revert "Add basic loop fusion pass."

2019-04-17T02:12:23+00:00

As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546

Canonicalize the representation of empty an expression in DIGlobalVariableExpression

2017-08-30T18:06:51+00:00

This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' will catch 95%. llvm-svn: 312144

Remove the obsolete offset parameter from @llvm.dbg.value

2017-07-28T20:21:02+00:00

There is no situation where this rarely-used argument cannot be substituted with a DIExpression and removing it allows us to simplify the DWARF backend. Note that this patch does not yet remove any of the newly dead code. rdar://problem/33580047 Differential Revision: https://reviews.llvm.org/D35951 llvm-svn: 309426

[StripDeadDebug/DIFinder] Track inlined SPs

2017-04-11T13:32:11+00:00

Summary: In rL299692 I improved strip-dead-debug-info's ability to drop CUs that are not referenced from the current module. However, in doing so I neglected to realize that some SPs could be referenced entirely from inlined functions. It appears I was not the only one to make this mistake, because DebugInfoFinder, doesn't find those SPs either. Fix this in DebugInfoFinder and then use that to make sure not to drop those CUs in strip-dead-debug-info.

[StripDeadDebugInfo] Drop dead CUs entirely

2017-04-06T19:26:22+00:00

Summary: Prior to this while it would delete the dead DIGlobalVariables, it would leave dead DICompileUnits and everything referenced therefrom. For a bit bitcode file with thousands of compile units those dead nodes easily outnumbered the real ones. Clean that up.

Renumber testcase metadata nodes after r290153.

2016-12-22T00:45:21+00:00

This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

[IR] Remove the DIExpression field from DIGlobalVariable.

2016-12-20T02:09:43+00:00

This patch implements PR31013 by introducing a DIGlobalVariableExpression that holds a pair of DIGlobalVariable and DIExpression. Currently, DIGlobalVariables holds a DIExpression. This is not the best way to model this: (1) The DIGlobalVariable should describe the source level variable, not how to get to its location. (2) It makes it unsafe/hard to update the expressions when we call replaceExpression on the DIGLobalVariable. (3) It makes it impossible to represent a global variable that is in more than one location (e.g., a variable with multiple DW_OP_LLVM_fragment-s). We also moved away from attaching the DIExpression to DILocalVariable for the same reasons. This reapplies r289902 with additional testcase upgrades and a change to the Bitcode record for DIGlobalVariable, that makes upgrading the old format unambiguous also for variables without DIExpressions. https://llvm.org/bugs/show_bug.cgi?id=31013 Differential Revision: https://reviews.llvm.org/D26769 llvm-svn: 290153

Revert "[IR] Remove the DIExpression field from DIGlobalVariable."

2016-12-16T19:39:01+00:00

This reverts commit 289920 (again). I forgot to implement a Bitcode upgrade for the case where a DIGlobalVariable has not DIExpression. Unfortunately it is not possible to safely upgrade these variables without adding a flag to the bitcode record indicating which version they are. My plan of record is to roll the planned follow-up patch that adds a unit: field to DIGlobalVariable into this patch before recomitting. This way we only need one Bitcode upgrade for both changes (with a version flag in the bitcode record to safely distinguish the record formats). Sorry for the churn! llvm-svn: 289982
