[PATCH v2] newlib: skip build of AArch64 80bit and 128bit long double functions when sizeof(double) == sizeof(long double)

Hello.

Thank you for your insights.

As far as I understand it, the error originates from `newlib/libm/ld/invtrig.h` header, that does not seem to support/handle `__LDBL_MANT_DIG__ 53`, which is included in e.g. `newlib/libm/ld/e_asinl.c` file. This file is added to the build by `newlib/libm/ld/Makefile.inc` file which is included to `newlib/libm/Makefile.inc` based on `HAVE_FPMATH_H` macro. This macro is set by result of `test -r "${srcdir}/libc/machine/${machine_dir}/machine/_fpmath.h"` command.

It does not seem that the `_LDBL_EQ_DBL` macro is involved in the decision whether the affected implementations should be built or any similar decision throughout the codebase.

In context of this, should I interpret your insights that the test for `_LDBL_EQ_DBL` should be added to the `HAVE_FPMATH_H` condition as the following version of the patch demonstrates?

Thank you for any further explanation.

Radek

Subject: [PATCH v2] newlib: skip build of AArch64 80bit and 128bit long double
 functions when sizeof(double) == sizeof(long double)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On aarch64-pc-cygwin and aarch64-w64-mingw, sizeof(double) ==
sizeof(long double) == 64 bit. This situation is detected by the
configure and signaled with _LDBL_EQ_DBL macro.

This patch skips build of objects from newlib/libm/ld/Makefile.inc when
this macro is set.

The newlib/Makefile.in file was updated using autoreconf-2.69 command.

v2-0001-newlib-skip-build-of-AArch64-80bit-and-128bit-long-double-functions.patch (application/octet-stream, 29.6 KB) 
From 249b223435ac396cbe60443af51e8b79af64659b Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Radek=20Barto=C5=88?= <[email protected]>
Date: Wed, 16 Jul 2025 14:56:19 +0200
Subject: [PATCH v2] newlib: skip build of AArch64 80bit and 128bit long double
 functions  when sizeof(double) == sizeof(long double)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On aarch64-pc-cygwin and aarch64-w64-mingw, sizeof(double) ==
sizeof(long double) == 64 bit. This situation is detected by the
configure and signaled with _LDBL_EQ_DBL macro.

This patch skips build of objects from newlib/libm/ld/Makefile.inc when
this macro is set.

The newlib/Makefile.in file was updated using autoreconf-2.69 command.
