Peter Michael Green db80cfb906 round to storage format in some tests before comparison to prevent spurious errors on x87. 2022-01-04 20:30:43 +00:00
Peter Michael Green fa70d9bda7 Add forced rounding to storage format for x87 to rem_pio2.rs as well. 2022-01-04 20:30:43 +00:00
Peter Michael Green 16ce35bb19 Use force_eval instead of to_bits/from_bits combination, 
Using to_bits/from_bits to force conversion to storage format
apparently doesn't work in release mode. Also add an architecture
conditional to avoid pessimising other architectures.

Alex Crichton fe396e00b7 Use macros for more division/array checks (#244) 
* Use macros for more division/array checks

This commit moves over more array accesses to the `i!` macro to avoid
bounds checks when debug assertions are disabled. This is surfaced from
rust-lang/compiler-builtins#360 where recent changes in codegen units
has caused some bounds checks to not get elided in release mode. This
also adds a `div!` macro to work around rust-lang/rust#72751.

* Don't test/bench our shim crate

It's not intended to run all our tests

AJ Frantz e149ec36ef Fix sincosf for interval (7*pi/4, 9*pi/4) (#233) 
A mistake was made in porting musl's implementation which caused the sin
and cos components to be reversed.

closes #232

Christopher Serr a5e39d8f1a Fix sincosf(PI) (#229) 
Looks like the implementation was not ported correctly. Some negations
were forgotten in a certain branch. Here is the original code in musl
that has the negations:

Alex Crichton a0a5bd85c9 Remove most #[inline] annotations 
These annotations fall into a few categories

* Some simply aren't needed since functions will always be in the same
  CGU anyway and are already candidates for inlining.
* Many are on massive functions which shouldn't be inlined across crates
  due to code size concerns.
* Others aren't necessary since calls to this crate are rarely inlined
  anyway (since it's lowered through LLVM).

If this crate is called directly and inlining is needed then LTO can
always be turned on, otherwise this will benefit downstream consumers by
avoiding re-codegen'ing so many functions.
