llc/MIR: Fix setFunctionAttributes for MIR functions

2020-01-06T22:21:51+00:00

A random set of attributes are implemented by llc/opt forcing the string attributes on the IR functions before processing anything. This would not happen for MIR functions, which have not yet been created at this point. Use a callback in the MIR parser, purely to avoid dealing with the ugliness that the command line flags are in a .inc file, and would require allowing access to these flags from multiple places (either from the MIR parser directly, or a new utility pass to implement these flags). It would probably be better to cleanup the flag handling into a separate library. This is in preparation for treating more command line flags with a corresponding function attribute in a more uniform way. The fast math flags in particular have a messy system where the command line flag sets the behavior from a function attribute if present, and otherwise the command line flag. This means if any other pass tries to inspect the function attributes directly, it will be inconsistent with the intended behavior. This is also inconsistent with the current behavior of -mcpu and -mattr, which overwrites any pre-existing function attributes. I would like to move this to consistenly have the command line flags not overwrite any pre-existing attributes, and to always ensure the command line flags are consistent with the function attributes.

Move CodeGenFileType enum to Support/CodeGen.h

2019-11-14T00:39:34+00:00

Avoids the need to include TargetMachine.h from various places just for an enum. Various other enums live here, such as the optimization level, TLS model, etc. Data suggests that this change probably doesn't matter, but it seems nice to have anyway.

Sink all InitializePasses.h includes

2019-11-14T00:34:37+00:00

This file lists every pass in LLVM, and is included by Pass.h, which is very popular. Every time we add, remove, or rename a pass in LLVM, it caused lots of recompilation. I found this fact by looking at this table, which is sorted by the number of times a file was changed over the last 100,000 git commits multiplied by the number of object files that depend on it in the current checkout: recompiles touches affected_files header 342380 95 3604 llvm/include/llvm/ADT/STLExtras.h 314730 234 1345 llvm/include/llvm/InitializePasses.h 307036 118 2602 llvm/include/llvm/ADT/APInt.h 213049 59 3611 llvm/include/llvm/Support/MathExtras.h 170422 47 3626 llvm/include/llvm/Support/Compiler.h 162225 45 3605 llvm/include/llvm/ADT/Optional.h 158319 63 2513 llvm/include/llvm/ADT/Triple.h 140322 39 3598 llvm/include/llvm/ADT/StringRef.h 137647 59 2333 llvm/include/llvm/Support/Error.h 131619 73 1803 llvm/include/llvm/Support/FileSystem.h Before this change, touching InitializePasses.h would cause 1345 files to recompile. After this change, touching it only causes 550 compiles in an incremental rebuild. Reviewers: bkramer, asbirlea, bollu, jdoerfert Differential Revision: https://reviews.llvm.org/D70211

[NFC] Add SUPPORT_PLUGINS to add_llvm_executable()

2019-11-06T19:32:35+00:00

Summary: this allows us to move logic about when it is appropriate set LLVM_NO_DEAD_STRIP out of each tool and into add_llvm_executable, which will enable future platform specific handling.

[NFC] Rename LLVM_NO_DEAD_STRIP

2019-10-25T13:32:00+00:00

Summary: The variable LLVM_NO_DEAD_STRIP is set in LLVM cmake files when building executables that might make use of plugins .The name of the variable does not convey the actual intended usage (i.e. for use with tools that have plugins), just what the eventual effect of setting in on some (i.e. not garbage collecting unused symbols). This patch renames it to LLVM_SUPPORT_PLUGINS to convey the intended usage, which will allow subsequent patches to add behavior to support that in different ways without confusion about whether it will do on, for example, non-gnu platforms.

[llvm] Migrate llvm::make_unique to std::make_unique

Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
