2018-12-25Remove licensesMark Rousskov-70/+0
2018-12-18Search other library paths when loking for link objectsPetr Hosek-5/+19
Support the case when link objects are not located in Rust sysroot but in other locations which could be specify through library paths.
2018-12-12Replace `FileSearch::for_each_lib_search_path` with `search_paths`.Nicholas Nethercote-8/+4
Returning an iterator leads to nicer code all around.
2018-12-12Introduce `SearchPath` and replace `SearchPaths` with `Vec<SearchPath>`.Nicholas Nethercote-6/+6
It's more idiomatic, makes the code shorter, and will help with the next commit.
2018-12-12Remove `Session::sysroot()`.Nicholas Nethercote-2/+1
Instead of maybe storing its own sysroot and maybe deferring to the one in `Session::opts`, just clone the latter when necessary so one is always directly available. This removes the need for the getter.
2018-12-07Various minor/cosmetic improvements to codeAlexander Regueiro-5/+5
2018-12-04Serialize modules into ThinBuffer after initial optimizationNikita Popov-32/+33
Instead of keeping all modules in memory until thin LTO and only serializing them then, serialize the module immediately after it finishes optimizing.
2018-12-04Remove unnecessary parts of run_fat_lto signatureNikita Popov-12/+5
Fat LTO merges into one module, so only return one module.

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.
2018-12-01Rollup merge of #56341 - frewsxcv:frewsxcv-util-cstr, r=Mark-Simulacrumkennytm-5/+5

2018-11-25Rollup merge of #56075 - alexcrichton:wasm-producer-section, r=estebankPietro Albini-0/+112
Encode a custom "producers" section in wasm files This commit implements WebAssembly/tool-conventions#65 for wasm files produced by the Rust compiler. This adds a bit of metadata to wasm modules to indicate that the file's language includes Rust and the file's "processed-by" tools includes rustc. The thinking with this section is to eventually have telemetry in browsers tracking all this.
2018-11-22Pass additional linker flags when targeting FuchsiaPetr Hosek-1/+9
This is a follow up to 8aa9267 which changed the driver to use lld directly rather than invoking it through Clang. This change ensures we pass all the necessary flags to lld.

2018-11-06Run name-anon-globals after LTO passes as wellNikita Popov-2/+13
If we're going to emit bitcode (through ThinLTOBuffer), then we need to ensure that anon globals are named. This was already done after optimization passes, but also has to happen after LTO passes, as we always emit the final result in a ThinLTO-compatible manner. Fixes #51947.
2018-11-05Remove support for building against LLVM 4Nikita Popov-3/+1
With emscripten removed in #55626, we no longer need to support building against LLVM 4.

Remove checks for LLVM < 4.0 While we still have to support LLVM 4.0 for Emscripten, we can drop checks for LLVM >= 4.0 and < 4.0.
