Liam Swayne	f857bf72e2	Add branchHint to std.math.pow ... NaN is an unlikely case, and a branchHint `.unlikely` could be appropriate.	2024-12-18 05:30:08 -05:00
Alex Rønne Petersen	047311a76a	std.math: Disable isSignalNan test on mips32. ... https://github.com/ziglang/zig/issues/14366	2024-11-26 18:29:13 +01:00
Chris Boesch	87863a834b	std.math.complex: Add squared magnitude function (#21998)	2024-11-26 13:03:48 +00:00
Alex Rønne Petersen	c9e67e71c1	std.Target: Replace isARM() with isArmOrThumb() and rename it to isArm(). ... The old isARM() function was a portability trap. With the name it had, it seemed like the obviously correct function to use, but it didn't include Thumb. In the vast majority of cases where someone wants to ask "is the target Arm?", Thumb *should* be included. There are exactly 3 cases in the codebase where we do actually need to exclude Thumb, although one of those is in Aro and mirrors a check in Clang that is itself likely a bug. These rare cases can just add an extra isThumb() check.	2024-11-03 09:29:30 +01:00
Krzysztof Wolicki	b1eaed6c8d	Remove packed_int_array usage from WasmPageAllocator and BigInt	2024-10-12 12:55:35 +02:00
Alex Rønne Petersen	1e838eba75	std.math: Re-enable isSignalNan test on most targets. ... This remains disabled on arm, aarch64, and powerpc, as well as for the C backend, as it still fails for these targets. See: https://github.com/ziglang/zig/issues/14366	2024-10-03 04:38:53 +02:00
Alex Rønne Petersen	c13713dd02	std.math: Re-enable snan() test. ... This now passes on all targets that we test in CI. See: https://github.com/ziglang/zig/issues/14366	2024-10-02 04:08:24 +02:00
Fri3dNstuff	b2c53eb0d7	std.math: change gcd's implementation to use Stein's algorithm instead of Euclid's (#21077)	2024-09-23 17:15:57 -07:00

Ian Johnson	3543f28320	std.math.big.int: fix shiftRight sign handling ... Closes #21311 The sign of the result `r` needs to be initialized before the correction `r.addScalar(r.toConst(), -1)`, or the intended end result could be off by 2 (depending on the original sign of `r`).	2024-09-06 10:36:12 -07:00
Jeremy Hertel	227fb4875f	std.math: rename make_f80 to F80.toFloat and break_f80 to F80.fromFloat	2024-09-02 00:10:22 +03:00
mlugg	0fe3fd01dd	std: update std.builtin.Type fields to follow naming conventions ... The compiler actually doesn't need any functional changes for this: Sema does reification based on the tag indices of `std.builtin.Type` already! So, no zig1.wasm update is necessary. This change is necessary to disallow name clashes between fields and decls on a type, which is a prerequisite of #9938.	2024-08-28 08:39:59 +01:00
mlugg	018262d537	std: update eval branch quotas after bdbc485 ... Also, update `std.math.Log2Int[Ceil]` to more efficient implementations that don't use up so much damn quota!	2024-08-21 01:30:46 +01:00
Jacob Young	ef11bc9899	Dwarf: rework self-hosted debug info from scratch ... This is in preparation for incremental and actually being able to debug executables built by the x86_64 backend.	2024-08-16 15:22:55 -04:00

Marc Tiehuis	2bd7af63d7	std.math.complex: fix acosh/atan/cosh/sqrt ... Some of these are upstream changes since the original port, others are translation errors.	2024-07-30 15:38:00 +12:00

Sean	a2df84d0ff	std.math: rework modf ... - Changed `modf_result` to `Modf` to better fit naming conventions - Reworked `modf` to be far simpler and support all floating point types (as well as vectors) (I have done benchmarks and can confirm that the performance is roughly equivalent to the old implementation) - Added more descriptive tests for modf - Deprecated `modf32_result` and `modf64_result` in favor of `Modf(f32)` and `Modf(f64)` respectively	2024-03-29 09:33:57 +00:00
Sean	f32723a237	Update frexp.zig (#19370) ... 1. Entirely rewrote frexp with generics, reducing the implementation to a single function and enabling parameters of types f80 and f16 2. Expanded upon the tests, making them more descriptive and comprehensive, and automatically generating the test bodies for each floating point type 3. Added a doctest for frexp	2024-03-21 18:08:52 -04:00

Ryan Liptak	16b3d1004e	Remove redundant test name prefixes now that test names are fully qualified ... Follow up to #19079, which made test names fully qualified. This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit: "priority_queue.test.std.PriorityQueue: shrinkAndFree" and the same test's name after the changes in this commit: "priority_queue.test.shrinkAndFree"	2024-02-26 15:18:31 -08:00
