2019-12-03Duplicate CrateConfig into SessionMark Rousskov-1/+3
Since it's just a type alias this isn't too difficult and once Session is moved back we can make this be the canonical location.

2019-11-26Rollup merge of #66719 - Mark-Simulacrum:int-normalization, r=CentrilTyler Mandry-9/+7
Store pointer width as u32 on Config This removes the dependency on IntTy, UintTy from Session. It's not obviously a win, but it seems a bit odd to store the AST IntTy/UintTy in Session, rather we store the pointer width as an integer and add normalization methods to IntTy and UintTy.

Add support for sanitizer recover and tracking origins of uninitialized memory * Add support for sanitizer recovery `-Zsanitizer-recover=...` (equivalent to `-fsanitize-recover` in clang). * Add support for tracking origins of uninitialized memory in MemorySanitizer `-Zsanitizer-memory-track-origins` (equivalent to `-fsanitize-memory-track-origins` in clang).

2019-11-22Rollup merge of #66575 - Mark-Simulacrum:no-uii, r=petrochenkovMazdak Farrokhzad-110/+7
Remove pretty printing of specific nodes in AST The ability to print a specific item as identified by NodeId or path seems not particularly useful, and certainly carries quite a bit of complexity with it. This is intended to simplify our CLI parsing a bit and remove a non-uncomplicated piece of it; I largely did this to remove the dependency on NodeId from librustc/session but it's not really necessary to do so in this invasive a way. The alternative is moving it to librustc_interface or driver, probably.

2019-11-19Mark -Zgenerate-arange-section as TRACKEDJosh Stone-1/+1
2019-11-18Generate DWARF address ranges for faster lookupsJosh Stone-0/+2
This adds a new option `-Zgenerate-arange-section`, enabled by default, corresponding to LLVM's `-generate-arange-section`. This creates a `.debug_aranges` section with DWARF address ranges, which some tools depend on to optimize address lookups (elfutils [22288], [25173]). This only has effect when debuginfo is enabled, and the additional data is small compared to the other debug sections. For example, libstd.so with full debuginfo is about 11MB, with just 61kB in aranges. [22288]: https://sourceware.org/bugzilla/show_bug.cgi?id=22288 [25173]: https://sourceware.org/bugzilla/show_bug.cgi?id=25173 Closes #45246.

Split non-CAS atomic support off into target_has_atomic_load_store This PR implements my proposed changes in https://github.com/rust-lang/rust/issues/32976#issuecomment-518542029 by removing `target_has_atomic = "cas"` and splitting `target_has_atomic` into two separate `cfg`s: * `target_has_atomic = 8/16/32/64/128`: This indicates the largest width that the target can atomically CAS (which implies support for all atomic operations). * ` target_has_atomic_load_store = 8/16/32/64/128`: This indicates the largest width that the target can support loading or storing atomically (but may not support CAS). cc #32976 r? @alexcrichton

2019-10-10Auto merge of #59546 - sfanxiang:interminable-ub, r=nagisabors-0/+3
Add llvm.sideeffect to potential infinite loops and recursions LLVM assumes that a thread will eventually cause side effect. This is not true in Rust if a loop or recursion does nothing in its body, causing undefined behavior even in common cases like `loop {}`. Inserting llvm.sideeffect fixes the undefined behavior. As a micro-optimization, only insert llvm.sideeffect when jumping back in blocks or calling a function. A patch for LLVM is expected to allow empty non-terminate code by default and fix this issue from LLVM side. https://github.com/rust-lang/rust/issues/28728 **UPDATE:** [Mentoring instructions here](https://github.com/rust-lang/rust/pull/59546#issuecomment-515072429) to unstall this PR

2019-10-01Rollup merge of #64722 - Mark-Simulacrum:alt-parallel, r=alexcrichtonTyler Mandry-3/+16
Make all alt builders produce parallel-enabled compilers We're not quite ready to ship parallel compilers by default, but the alt builders are not used too much (in theory), so we believe that shipping a possibly-broken compiler there is not too problematic. r? @nikomatsakis
2019-09-30Make the default parallelism 1Mark Rousskov-3/+16
This changes the default parallelism for parallel compilers to one, instead of the previous default, which was "num cpus". This is likely not an optimal default long-term, but it is a good default for testing whether parallel compilers are not a significant regression over a sequential compiler. Notably, this in theory makes a parallel-enabled compiler behave exactly like a sequential compiler with respect to the jobserver.
