v2 fixes:
change log entries config/rs6000/vsx.md, config/rs6000/rs6000-builtin.def,
config/rs6000/rs6000-call.c.
gcc/config/rs6000/rs6000-call.c: fixed if check for 3rd arg between 0 and 3
fixed if check for 3rd arg between 0 and 12
gcc/config/rs6000/vsx.md: removed REPLACE_ELT_atr definition and used
VS_scalar instead.
removed REPLACE_ELT_inst definition and used <mode> i\
nstead
fixed spelling mistake on Endianness.
fixed indenting for vreplace_elt_<mode>
-----------------------------------
GCC maintainers:
The following patch adds support for builtins vec_replace_elt and
vec_replace_unaligned.
The patch has been compiled and tested on
powerpc64le-unknown-linux-gnu (Power 9 LE)
and mambo with no regression errors.
Please let me know if this patch is acceptable for the pu
branch. Thanks.
Carl Love
