With Fortran adding support for changing the long double format, this patch removes the code that only allowed C/C++ to change the long double format for GLIBC 2.32 and later without a warning. I have bootstraped the compiler with this change and there where no regressesion. In addition, I have applied it to the power-ieee128 branch where the work is being done to add support for both types of 128-bit floating point on PowerPC. If I build a compiler from that branch, I can change the 128-bit floating point format at compile time. Can I check this patch into the trunk GCC compiler? gcc/ 2022-01-12 Michael Meissner * config/rs6000/rs6000.c (rs6000_option_override_internal): Remove checks for only C/C++ front ends before allowing the long double format to change without a warning. --- gcc/config/rs6000/rs6000.c | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) diff --git a/gcc/config/rs6000/rs6000.c b/gcc/config/rs6000/rs6000.c index 319182e94d9..0e3481c8327 100644 --- a/gcc/config/rs6000/rs6000.c +++ b/gcc/config/rs6000/rs6000.c @@ -4221,13 +4221,11 @@ rs6000_option_override_internal (bool global_init_p) if (rs6000_ieeequad != TARGET_IEEEQUAD_DEFAULT && TARGET_LONG_DOUBLE_128) { /* Determine if the user can change the default long double type at - compilation time.
