AMDGPU: Fix assert on dbg_value instructions llvm-svn: 244728

AMDGPU: Rework how private buffer passed for HSA If we know we have stack objects, we reserve the registers that the private buffer resource and wave offset are passed and use them directly. If not, reserve the last 5 SGPRs just in case we need to spill. After register allocation, try to pick the next available registers instead of the last SGPRs, and then insert copies from the inputs to the reserved registers in the progloue. This also only selectively enables all of the input registers which are really required instead of always enabling them. llvm-svn: 254331

DI: Reverse direction of subprogram -> function edge. Previously, subprograms contained a metadata reference to the function they described. Because most clients need to get or set a subprogram for a given function rather than the other way around, this created unneeded inefficiency. For example, many passes needed to call the function llvm::makeSubprogramMap() to build a mapping from functions to subprograms, and the IR linker needed to fix up function references in a way that caused quadratic complexity in the IR linking phase of LTO. This change reverses the direction of the edge by storing the subprogram as function-level metadata and removing DISubprogram's function field. Since this is an IR change, a bitcode upgrade has been provided. Fixes PR23367. An upgrade script for textual IR for out-of-tree clients is attached to the PR.

DI: Require subprogram definitions to be distinct As a follow-up to r246098, require `DISubprogram` definitions (`isDefinition: true`) to be 'distinct'. Specifically, add an assembler check, a verifier check, and bitcode upgrading logic to combat testcase bitrot after the `DIBuilder` change. While working on the testcases, I realized that test/Linker/subprogram-linkonce-weak-odr.ll isn't relevant anymore. Its purpose was to check for a corner case in PR22792 where two subprogram definitions match exactly and share the same metadata node. The new verifier check, requiring that subprogram definitions are 'distinct', precludes that possibility. I updated almost all the IR with the following script: git grep -l -E -e '= !DISubprogram\(.* isDefinition: true' | grep -v test/Bitcode | xargs sed -i '' -e 's/= \(!DISubprogram(.*, isDefinition: true\)/= distinct \1/' Likely some variant of would work for out-of-tree testcases. llvm-svn: 246327
