v3 fixes:
Minor cleanup in the ChangeLog description.
-------------------------------------------------
v2 fixes:
change log fixes
gcc/config/rs6000/altivec changed name of define_insn and define_expand
for vxxspltiw... to xxspltiw... Fixed spaces in gen_xxsplti32dx_v4sf_inst
(operands[0], GEN_INT
gcc/rs6000-builtin.def propagated name changes above where they are used.
Updated definition for S32bit_cint_operand, c32bit_cint_operand,
f32bit_const_operand predicate definitions.
Changed name of rs6000_constF32toI32 to rs6000_const_f32_to_i32, propagated
name change as needed. Replaced if test with gcc_assert().
Fixed description of vec_splatid() in documentation.
-----------------------
GCC maintainers:
The following patch adds support for the vec_splati, vec_splatid and
vec_splati_ins builtins.
This patch adds support for instructions that take a 32-bit immediate
value that represents a floating point value. This support adds new
predicates and a support function to properly handle the immediate value.
The patch has been compiled and tested on
powerpc64le-unknown-linux-gnu (Power 9 LE)
with no regression errors.
The test case was compiled on a Power 9 system and then tested on
Mambo.
Please let me know if this patch is acceptable for the mainline
branch. Thanks.
