Bug ID: 96253
Summary: decimal floating point missing on ARM
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: tydeman at tybor dot com
Target Milestone: ---
Based on the output of "gcc $CFLAGS -E -dM hello.c", I see that most of the
_Decimal32/64/128 related values are defined for ARM -std=gnu2x
-mcpu=cortex-a72 when I use gcc 9.3.0 on an ARM based computer. Yet, when I
try to use _Decimal32/64/128 as a floating-point type, I get the error:
decimal floating point not supported for this target. Assuming decimal
floating point is supported for some version of ARM, what command line options
(or other things) do I need to get it? It would be nice if the online gcc
documentation said which targets do support decimal floating point.
