2019-12-02Use Module::print() instead of a PrintModulePassVictor Ding-8/+5
llvm::Module has a print() method. It is unnecessary to create a pass just for the purpose of printing LLVM IR.

2019-11-29Use LLVMAddAnalysisPasses instead of Rust's wrapperVictor Ding-3/+3
LLVM exposes a C API `LLVMAddAnalysisPasses` and hence Rust's own wrapper `LLVMRustAddAnalysisPasses` is not needed anymore.

2019-10-29Allow specifying key "llvm-abiname" in target specificationGui Andrade-1/+2
This addresses #65024, as it allows RISC-V target specification files to set "llvm-abiname": "lp64d". In general, it is useful for the programmer to be able to set this codegen parameter, which other languages usually expose under a compiler argument like "-mabi=<XYZ>".

2019-07-15Don't add extra passes into the function pass managerNikita Popov-39/+49
Exception for specific cases like linting, additional passes should be going into the module pass manager (even if they are function passes). The separate function pass manager is only used for very early optimization passes. Rather than apparending passes to the MPM, use the OptimizerLast and EnabledOnOptLevel0 pass manager builder extension hooks, which allow adding passes directly before finalization (alias canonicalization and name-anon-globals). The main effect and purpose of this change is to add sanitizer passes at the end of the pipeline, which is where they belong. In LLVM 9 the address sanitizer can't be used as a pass in the early function pass manager, because it has a dependence on a module-level analysis pass.

2019-04-14Rollup merge of #59874 - michaelwoerister:pgo-updates-1, r=cramertjMazdak Farrokhzad-6/+16
Clean up handling of `-Z pgo-gen` commandline option. This PR adapts the `-Z pgo-gen` flag to how Clang and GCC handle the corresponding `-fprofile-generate` flag. In particular, the flag now optionally takes a directory to place the profiling data in and allows to omit the argument (instead of having to pass an empty string).
2019-04-14Rollup merge of #59812 - michaelwoerister:profile-gen-msvc-imp, r=alexcrichtonMazdak Farrokhzad-1/+17
Exclude profiler-generated symbols from MSVC __imp_-symbol workaround. LLVM's profiling instrumentation adds a few symbols that are used by the profiler runtime. Since these show up as globals in the LLVM IR, the compiler generates `dllimport`-related `__imp_` stubs for them. This can lead to linker errors because the instrumentation symbols have weak linkage or are in a comdat section, but the `__imp_` stubs aren't. Instead of trying to replicate the linkage/comdat setup for the stubs, this PR just excludes the profiler-related symbols from stub-generation since they aren't supposed to be referenced via `__declspec(dllimport)` anywhere anyway. r? @alexcrichton EDIT: I considered making this more general, i.e. inferring from the symbol name if it is a Rust symbol or not. But then I figured out that that would yield false negatives for `#[no_mangle]` et al, so I went with a blacklist approach.

I was trying to output LLVM IR directly to the console: $ rustc hello.rs --emit=llvm-ir -o /dev/stdout LLVM ERROR: IO failure on output stream: Bad file descriptor Now `LLVMRustPrintModule` returns an error, and we print: error: failed to write LLVM IR to /dev/stdout.hello.7rcbfp3g-cgu.0.rcgu.ll: Permission denied ... which is more informative.

2018-12-03Auto merge of #56358 - nikic:mergefunc-aliases, r=rkruppebors-4/+5
Enable -mergefunc-use-aliases If the Rust LLVM fork is used, enable the -mergefunc-use-aliases flag, which will create aliases for merged functions, rather than inserting a call from one to the other. A number of codegen tests needed to be adjusted, because functions that previously fell below the thunk limit are now being merged. Merging is prevented in various ways now. I expect that this is going to break something, somewhere, because it isn't able to deal with aliases properly, but we won't find out until we try :) This fixes #52651. r? @rkruppe
2018-12-02Run name-anon-globals after all other passesNikita Popov-4/+5
name-anon-globals should always be run at the very end of the pass pipeline, as optimization passes (in particular mergefunc) may introduce new anonymous globals. I believe we did not run into this earlier because it requires the rather specific combination of a) mergefunc merging two weak functions b) compilation not using thinlto.
