Dan Halbert 2c0fa0f7dc initial merge from v1.20.0; just satisifying conflicts 2023-09-19 11:10:12 -04:00
David Lechner 0eead94181 lib/libm: Use __asm__ instead of asm. 
`asm` is not part of the C standard and causes a complier error when
`-std=c99` is used. `__asm__` is the recommended alternative.

Zoltán Vörös 27767aafa2 lib/libm_dbl: Add round.c source code. 
This code is imported from musl, to match existing code in libm_dbl.

The file is also added to the build in stm32/Makefile.  It's not needed by
the core code but, similar to c5cc64175b,
allows round() to be used by user C modules or board extensions.

Diego Elio Pettenò dd5d7c86d2 Fix up end of file and trailing whitespace. 
This can be enforced by pre-commit, but correct it separately to make it easier to review.

Jim Mussared 580a2656d1 stm32: Use hardware double sqrt on F7/H7 MCUs. 
Identical to cd527bb324 but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.

Andrew Leech 57a73973ad lib/libm_dbl: Add implementation of copysign() for DEBUG builds. 
This provides a double variant of the float copysignf from libm/math.c
which is required for DEBUG=1 builds when MICROPY_FLOAT_IMPL=double

Damien George 0b239d458c lib/libm_dbl/tanh: Make tanh more efficient and handle large numbers. 
Prior to this patch tanh(large number) would return nan due to inf/inf.
