Re: [PATCH] soft-fp: Update soft-fp from glibc

[Kito Cheng via Gcc-patches]

Hi Joseph:

I saw other soft-fp updates will also ask for some approval on the
list too, anyway I know that now :)

Thanks!

[PATCH] soft-fp: Update soft-fp from glibc

[Kito Cheng]

This patch is updating all soft-fp from glibc, most changes are
copyright years update, removing "Contributed by" lines and update URL for
license, and changes other than those update are adding conversion
function between IEEE half and 32-bit/64-bit integer, those functions are
required by RISC-V _Float16 support.

[PATCH] soft-fp: Update soft-fp from glibc

[H.J. Lu via Gcc-patches]

From: liuhongt 

1. Add __extendhfdf2/__extendhfsf2 to return an IEEE half converted to
IEEE double/single.
2. Add __truncdfhf2/__extendsfhf2 to truncate IEEE double/single into
IEEE half.
3. Add __eqhf2/__nehf2 to return 0 if a == b and a,b are not NAN,
otherwise return 1.

These are needed by x86 _Float16.

* soft-fp/eqhf2.c: New file.
* soft-fp/extendhfdf2.c: Likewise.
* soft-fp/extendhfsf2.c: Likewise.
* soft-fp/truncdfhf2.c: Likewise.
* soft-fp/truncsfhf2.c: Likewise.
* soft-fp/half.h (FP_CMP_EQ_H): New.

[PATCH] soft-fp: Update soft-fp from glibc

[H.J. Lu]

This patch is updating all soft-fp from glibc, most changes are
copyright years update, and changes other than years update are

* soft-fp/extenddftf2.c: Use "_FP_W_TYPE_SIZE < 64" to check if
4_FP_W_TYPEs are used for IEEE quad precision.
* soft-fp/extendhftf2.c: Likewise.
* soft-fp/extendsftf2.c: Likewise.
* soft-fp/extendxftf2.c: Likewise.
* soft-fp/trunctfdf2.c: Likewise.
* soft-fp/trunctfhf2.c: Likewise.
* soft-fp/trunctfsf2.c: Likewise.
* soft-fp/trunctfxf2.c: Likewise.
* config/rs6000/ibm-ldouble.c: Likewise.

OK for trunk?

Thanks.

H.J.
