2016-09-12crate-ify compiler-rt into compiler-builtinsJorge Aparicio-0/+10
libcompiler-rt.a is dead, long live libcompiler-builtins.rlib This commit moves the logic that used to build libcompiler-rt.a into a compiler-builtins crate on top of the core crate and below the std crate. This new crate still compiles the compiler-rt instrinsics using gcc-rs but produces an .rlib instead of a static library. Also, with this commit rustc no longer passes -lcompiler-rt to the linker. This effectively makes the "no-compiler-rt" field of target specifications a no-op. Users of `no_std` will have to explicitly add the compiler-builtins crate to their crate dependency graph *if* they need the compiler-rt intrinsics. Users of the `std` have to do nothing extra as the std crate depends on compiler-builtins. Finally, this a step towards lazy compilation of std with Cargo as the compiler-rt intrinsics can now be built by Cargo instead of having to be supplied by the user by some other method. closes #34400

2016-09-12Auto merge of #36414 - nnethercote:char_lit, r=jseyfriedbors-19/+16
Improve char_lit's readability and speed This is my first contribution to rustc. Please let me know if I've done anything wrong. (I ran `make tidy` before making the pull request.)
2016-09-12Lazily construct panic messages in char_lit().Nicholas Nethercote-5/+7
This reduces the time taken to run `rustc -Zparse-only rustc-benchmarks/issue-32278-big-array-of-strings` from 0.18s to 0.15s on my machine, and reduces the number of instructions (as measured by Cachegrind) from 1.34B to 1.01B. With the change applied, the time to fully compile that benchmark is 1.96s, so this is a 1.5% improvement.
2016-09-12Avoid an unnecessary intermediate value in char_lit().Nicholas Nethercote-14/+9
This makes the function more concise and easier to understand.

macros: stackless expansion After this PR, macro expansion cannot overflow the stack unless the expanded crate is too deep to fold. Everything but the stackless placeholder expansion commit is also groundwork for macro modularization. r? @nrc or @eddyb

2016-09-06Auto merge of #36025 - michaelwoerister:incr-comp-hash-spans, r=nikomatsakisbors-20/+4
incr. comp.: Take spans into account for ICH This PR makes the ICH (incr. comp. hash) take spans into account when debuginfo is enabled. A side-effect of this is that the SVH (which is based on the ICHs of all items in the crate) becomes sensitive to the tiniest change in a code base if debuginfo is enabled. Since we are not trying to model ABI compatibility via the SVH anymore (this is done via the crate disambiguator now), this should be not be a problem. Fixes #33888. Fixes #32753.
