Subject: [Bug libgcc/97543] powerpc64le: libgcc has unexpected long double in .gnu_attribute
Date: Sat, 24 Oct 2020 07:32:21 +0000	[thread overview]
Message-ID: <bug-97543-4-lrIZGPojeg@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #8 from Michael Meissner <meissner at gcc dot gnu.org> ---
In addition to ibm-ldouble.c, the following functions set the gnu attribute #4
to 5 (i.e. pass/use IBM extended double as long double):

_divtc3
_fixtfdi
_fixunstfdi
_floatditf
_floatunditf
_multc3
_powitf2
ppc64-fp

This means we have to change the definition of TFmode and TCtype from:

typedef float TFtype __attribute__ ((mode (TF)));
typedef _Complex float TCtype __attribute__ ((mode (TC)));

to:

typedef float TFtype __attribute__ ((mode (IF)));
typedef _Complex float TCtype __attribute__ ((mode (IC)));
