FloatUtils: Replace quieting SNaNs via `0.0 + x` with MakeQuiet

2025-08-17T15:24:38+00:00

Replace Common::BitCast with std::bit_cast

2024-05-04T01:43:51+00:00

PowerPC: Negate m_dec values in frsqrte table

2023-10-21T19:08:21+00:00

This value is used in a multiplication. The result of this
multiplication is then subtracted from m_base. By negating m_dec, we are
free to use an addition instead.

On x64, this saves an instruction.

PowerPC: Flip the order of frsqrte_expected

2023-09-30T09:41:27+00:00

This makes the the frsqrte routines one instruction shorter.

treewide: convert GPLv2+ license info to SPDX tags

2021-07-05T02:35:56+00:00

SPDX standardizes how source code conveys its copyright and licensing
information. See https://spdx.github.io/spdx-spec/1-rationale/ . SPDX
tags are adopted in many large projects, including things like the Linux
kernel.

FloatUtils: Clean up memcpy usages

2018-05-10T16:28:09+00:00

Now that we have BitCast, we can use that instead.

FloatUtils: Remove union type punning from ClassifyX functions

2018-05-09T14:25:23+00:00

Type-punning via unions is undefined behavior in C++

Also take the liberty of cleaning these up a little bit by removing
unnecessary else usages.

FloatUtils: Remove union type punning from ApproximateReciprocal functions

2018-05-09T14:05:29+00:00

This form of type punning invokes undefined behavior in C++

FloatUtils: Remove using namespace std in ApproximateReciprocal()

2018-05-09T13:36:23+00:00

This was made quite a long time ago when we supported 32-bit ARM targets

Common: Move floating-point utility functions to FloatUtils.h/.cpp

2018-05-07T06:56:32+00:00

Keeps all of the floating-point utility functions in their own file to
keep them all together. This also provides a place for other
general-purpose floating-point functions to be added in the future,
which will be necessary when improving the flag-setting within the
interpreter.
