Latest `cc-rs` already manage all arm/thumb flags, so We can
safely remove this piece of code.

Alex Crichton 0703bfa725 Fix some `use_c_shim_if` directives 
This was an accidental regression introduced in #252 by removing compilation of
C files without adjusting the `#[use_c_shim_if]` directives. This restores the
compilation of the assembly files and updates the `#[use_c_shim_if]` directives.

Fix __sync_fetch_and_nand_* for pre-v6 ARM
 2018-08-18 22:16:49 -07:00
Adrian Bunk 8a0033ebfc Fix __sync_fetch_and_nand_* for pre-v6 ARM 
gcc changed semantics for __sync_fetch_and_nand_* in gcc 4.4,
and this was implementing the old semantics:

Fix symbol collision caused by `floatdisf`

Yu Ding bf370326cf Fix symbol collision caused by floatdisf 
[PR #234](https://github.com/rust-lang-nursery/compiler-builtins/pull/234) added floatdisf implementation in rust and removed floatdisf.c from build.rs. However the removal is in-complete. In x86_64+!msvc environment, the symbol floatdisf would be generated twice. Bugs found in Redox OS issue [#1195](https://gitlab.redox-os.org/redox-os/redox/issues/1195) and Mesalink travis [log](https://travis-ci.org/mesalock-linux/mesalink/jobs/412928048) at line 738. This patch fixes it by removing floatdisf.c from this environment.

Alex Crichton 5d370bb352 Don't build multc3 on AArch64 MSVC 
Apparently it doesn't compile due to an odd compiler error! This intrinsic has
to do with complex arithmetic anyway and we shouldn't need it.
