RFC: powerpc64le: Enable support for IEEE long double gabriel/powerpc-ieee128-printscan
Not for glibc-2.31 - Do not commit!
No changes since v3.
Changes since v2:
- Added definition of LDBL_IBM128_COMPAT_VERSION and
LDBL_IBM128_VERSION (moved from a previous commit).
Changes since v1:
- Use __LONG_DOUBLE_USES_FLOAT128 directly.
-- 8< --
On platforms where long double may have two different formats, i.e.: the
same format as double (64-bits) or something else (128-bits), building
with -mlong-double-128 is the default and function calls in the user
program match the name of the function in Glibc. When building with
-mlong-double-64, Glibc installed headers redirect such calls to the
appropriate function.
This patch adds similar redirections to be used by user code builds in
IEEE long double mode (-mabi=ieeelongdouble). It also skips some uses
of libc_hidden_proto in internal headers, because they also produce
redirections, causing a redirection conflict.
PS: Missing NEWS entry.
