Specifically, the following items are no longer part of its API: * DEFAULT_ERROR_CODE * backtrace * unwind * args * at_exit * cleanup * heap (this is just alloc::heap) * min_stack * util The module is now tagged as `#[doc(hidden)]` as the only purpose it's serve is an entry point for the `panic!` macro via the `begin_unwind` and `begin_unwind_fmt` reexports. 2015-09-03T06:49:50+00:00 Vadim Petrochenkov vadim.petrochenkov@gmail.com 2015-09-03T06:49:50+00:00 urn:sha1:06fb196256bbab1e7aa4f43daf45321efaa6e0eb 2015-08-17T21:41:37+00:00 Huon Wilson dbau.pp+github@gmail.com 2015-07-13T18:57:46+00:00 urn:sha1:c66554cab3518a9f5c36eafd622ca4c8a3fda631 This functionality will be available out of tree in the `simd` crate on crates.io.

This also additionally adds a few minor fixes here and there in the test harness and such to get `make check` entirely passing on 64-bit MSVC: * The invocation of `maketest.py` now works with spaces/quotes in CC * debuginfo tests are disabled on MSVC * A link error for librustc was hacked around (see #27438) 2015-08-10T23:40:54+00:00 bors bors@rust-lang.org 2015-08-10T23:40:54+00:00 urn:sha1:5aca49c693c9be3064d9e6db9473b1fa76834b79 This commit removes all morestack support from the compiler which entails: * Segmented stacks are no longer emitted in codegen. * We no longer build or distribute libmorestack.a * The `stack_exhausted` lang item is no longer required The only current use of the segmented stack support in LLVM is to detect stack overflow. This is no longer really required, however, because we already have guard pages for all threads and registered signal handlers watching for a segfault on those pages (to print out a stack overflow message). Additionally, major platforms (aka Windows) already don't use morestack. This means that Rust is by default less likely to catch stack overflows because if a function takes up more than one page of stack space it won't hit the guard page. This is what the purpose of morestack was (to catch this case), but it's better served with stack probes which have more cross platform support and no runtime support necessary. Until LLVM supports this for all platform it looks like morestack isn't really buying us much. cc #16012 (still need stack probes) Closes #26458 (a drive-by fix to help diagnostics on stack overflow) r? @brson 2015-08-10T23:35:44+00:00 Alex Crichton alex@alexcrichton.com 2015-07-27T20:41:35+00:00 urn:sha1:7a3fdfbf674a08b7f6fd32c9124e52924a2f9a1c This commit removes all morestack support from the compiler which entails: * Segmented stacks are no longer emitted in codegen. * We no longer build or distribute libmorestack.a * The `stack_exhausted` lang item is no longer required The only current use of the segmented stack support in LLVM is to detect stack overflow.
