DebugInfo: add a test case for data member locations (coverage for r193835) llvm-svn: 193878
2013-11-02 02:25:55 +08:00
; RUN: llc -mtriple=x86_64-linux -O0 -o - -filetype=obj < %s | llvm-dwarfdump -debug-dump=info -| FileCheck %s
Revert "Reverting r193835 due to weirdness with Go..." The cgo problem was that it wants dwarf2 which doesn't support direct constant encoding of the location. So let's add support for dwarf2 encoding (using a location expression) of data member locations. This reverts commit r198385. llvm-svn: 198389

DebugInfo: Improve readability of test case added in r193878 The point is to ensure that the attribute in question (DW_AT_data_member_location) is associated with the prior tag, so ensure that we don't see another tag starting between the intended tag and the desired attribute. llvm-svn: 193884

[dwarfdump] Pretty print location expressions and location lists Summary: Based on Fred's patch here: https://reviews.llvm.org/D6771 I can't seem to commandeer the old review, so I'm creating a new one. With that change the locations exrpessions are pretty printed inline in the DIE tree. The output looks like this for debug_loc entries: DW_AT_location [DW_FORM_data4] (0x00000000 0x0000000000000001 - 0x000000000000000b: DW_OP_consts +3 0x000000000000000b - 0x0000000000000012: DW_OP_consts +7 0x0000000000000012 - 0x000000000000001b: DW_OP_reg0 RAX, DW_OP_piece 0x4 0x000000000000001b - 0x0000000000000024: DW_OP_breg5 RDI+0) And like this for debug_loc.dwo entries: DW_AT_location [DW_FORM_sec_offset] (0x00000000 Addr idx 2 (w/ length 190): DW_OP_consts +0, DW_OP_stack_value Addr idx 3 (w/ length 23): DW_OP_reg0 RAX, DW_OP_piece 0x4) Simple locations without ranges are printed inline: DW_AT_location [DW_FORM_block1] (DW_OP_reg4 RSI, DW_OP_piece 0x4, DW_OP_bit_piece 0x20 0x0) The debug_loc(.dwo) dumping in changed accordingly to factor the code.

Renumber testcase metadata nodes after r290153. 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. Differential Revision: https://reviews.llvm.org/D27765 llvm-svn: 290292

IR: Make metadata typeless in assembly Now that `Metadata` is typeless, reflect that in the assembly. These are the matching assembly changes for the metadata/value split in r223802. - Only use the `metadata` type when referencing metadata from a call intrinsic -- i.e., only when it's used as a `Value`. - Stop pretending that `ValueAsMetadata` is wrapped in an `MDNode` when referencing it from call intrinsics. So, assembly like this: define @foo(i32 %v) { call void @llvm.foo(metadata !{i32 %v}, metadata !0) call void @llvm.foo(metadata !{i32 7}, metadata !0) call void @llvm.foo(metadata !1, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{metadata !3}, metadata !0) ret void, !bar !2 } !0 = metadata !{metadata !2} !1 = metadata !{i32* @global} !2 = metadata !{metadata !3} !3 = metadata !{} turns into this: define @foo(i32 %v) { call void @llvm.foo(metadata i32 %v, metadata !0) call void @llvm.foo(metadata i32 7, metadata !0) call void @llvm.foo(metadata i32* @global, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{!3}, metadata !0) ret void, !bar !2 } !0 = !{!2} !1 = !{i32* @global} !2 = !{!3} !3 = !{} I wrote an upgrade script that handled almost all of the tests in llvm and many of the tests in cfe (even handling many `CHECK` lines). I've attached it (or will attach it in a moment if you're speedy) to PR21532 to help everyone update their out-of-tree testcases. This is part of PR21532. llvm-svn: 224257
