e29e30b1 - [llvm-readobj] Change -long-option to --long-option in tests. NFC

Wed, 01 May 2019 05:27:20 +0000

[llvm-readobj] Change -long-option to --long-option in tests. NFCWe use both -long-option and --long-option in tests. Switch to --long-option for consistency.In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).llvm-svn: 359649 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/COFF/bitfields.ll

05782218 - Canonicalize the representation of empty an expression in DIGlobalVariableExpression

Wed, 30 Aug 2017 18:06:51 +0000

Canonicalize the representation of empty an expression in DIGlobalVariableExpressionThis change simplifies code that has to deal withDIGlobalVariableExpression and mirrors how we treat DIExpressions indebug info intrinsics. Before this change there were two ways ofrepresenting 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 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/COFF/bitfields.ll

1eadba1c - Renumber testcase metadata nodes after r290153.

Thu, 22 Dec 2016 00:45:21 +0000

Renumber testcase metadata nodes after r290153.This patch renumbers the metadata nodes in debug info testcases afterhttps://reviews.llvm.org/D26769. This is a separate patch because itcauses so much churn. This was implemented with a python script thatpipes the testcases through llvm-as - | llvm-dis - and then goesthrough the original and new output side-by side to insert allcomments at a close-enough location.Differential Revision: https://reviews.llvm.org/D27765llvm-svn: 290292 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/COFF/bitfields.ll

bceaaa96 - [IR] Remove the DIExpression field from DIGlobalVariable.

Tue, 20 Dec 2016 02:09:43 +0000

[IR] Remove the DIExpression field from DIGlobalVariable.This patch implements PR31013 by introducing aDIGlobalVariableExpression that holds a pair of DIGlobalVariable andDIExpression.Currently, DIGlobalVariables holds a DIExpression. This is not thebest 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 changeto the Bitcode record for DIGlobalVariable, that makes upgrading theold format unambiguous also for variables without DIExpressions.https://llvm.org/bugs/show_bug.cgi?id=31013Differential Revision: https://reviews.llvm.org/D26769llvm-svn: 290153 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/COFF/bitfields.ll

73ec0656 - Revert "[IR] Remove the DIExpression field from DIGlobalVariable."

Fri, 16 Dec 2016 19:39:01 +0000

Revert "[IR] Remove the DIExpression field from DIGlobalVariable."This reverts commit 289920 (again).I forgot to implement a Bitcode upgrade for the case where a DIGlobalVariablehas not DIExpression. Unfortunately it is not possible to safely upgradethese variables without adding a flag to the bitcode record indicating whichversion they are.My plan of record is to roll the planned follow-up patch that adds aunit: field to DIGlobalVariable into this patch before recomitting.This way we only need one Bitcode upgrade for both changes (with aversion flag in the bitcode record to safely distinguish the recordformats).Sorry for the churn!llvm-svn: 289982 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/COFF/bitfields.ll
