I'm backing out D68945, which as the discussion for D73526 shows, doesn't seem to handle the -O0 path through the codegen backend correctly. I'll reland the patch when a fix is worked out, apologies for all the churn. The two parent commits are part of this revert too. Conflicts: llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp llvm/test/DebugInfo/X86/dbg-addr-dse.ll SelectionDAGBuilder conflict is due to a nearby change in e39e2b4a79c6 that's technically unrelated. dbg-addr-dse.ll conflicted because 41206b61e30c (legitimately) changes the order of two lines. There are further modifications to dbg-value-func-arg.ll: it landed after the patch being reverted, and I've converted indirection to be represented by the isIndirect field rather than DW_OP_deref. (cherry picked from commit 6531a78ac4b5b229bce272706593a0bc873877d7) 2020-02-12T13:06:19+00:00 Jeremy Morse jeremy.morse@sony.com 2020-02-05T16:57:59+00:00 urn:sha1:04d7337d69fa38f00179811419207a9ef5eef83e This reverts commit 3137fe4d23eeb8df08c03e9111465325eeafe08e. I'm backing out D68945, which this patch is a follow up for. It'll be re-landed when D68945 is fixed. The changes to dbg-value-func-arg.ll occur because our handling of certain kinds of location now mixes up indirection that happens at different points in a DIExpression. While this is a regression, it's a return to the prior behaviour while a better patch is sought. (cherry picked from commit ece761427f63de96ee52bbd6be1c61b07967a917) 2020-02-12T13:04:24+00:00 Jeremy Morse jeremy.morse@sony.com 2020-02-04T14:19:42+00:00 urn:sha1:c1701728b93b3aec39d3b93d0182648887edfdb1 This patch reverts part of r362750 / D62650, which stopped LiveDebugVariables from trimming leading variable location ranges down to only covering those instructions that are in scope. I've observed some circumstances where the number of DBG_VALUEs in a function can be amplified in an un-necessary way, to cover more instructions that are out of scope, leading to very slow compile times. Trimming the range of instructions that the variables cover solves the slow compile times. The specific problem that r362750 tries to fix is addressed by the assignment to RStart that I've added. Any variable location that begins at the first instruction of a block will now be considered to begin at the start of the block. While these sound the same, the have different SlotIndexes, and the register allocator may shoehorn additional instructions in between the two. The test added in the past (wrong_debug_loc_after_regalloc.ll) still works with this modification. live-debug-variables.ll has a range trimmed to not cover the prologue of the function, while dbg-addr-dse.ll has a DBG_VALUE sink past one instruction with no DebugLoc, which is expected behaviour.
