GCC maintainers:
The following patch fixes the first argument in the builtin definition
and the corresponding test cases. Initially, the builtin specification
was wrong due to a cut and past error. The documentation was fixed in:

rs6000: Clean up ISA 3.1 documentation [PR100808]
Due to a pasto error in the documentation, vec_replace_unaligned was
implemented with the same function prototypes as vec_replace_elt. It was
intended that vec_replace_unaligned always specify output vectors as
having
type vector unsigned char, to emphasize that elements are potentially
misaligned by this built-in function. This patch corrects the
misimplementation.

PR target/100808
* doc/extend.texi (Basic PowerPC Built-in Functions Available on
ISA
3.1): Provide consistent type names. Remove unnecessary
semicolons.
Fix bad line breaks.
This patch fixes the arguments in the definitions and updates the
testcases accordingly. Additionally, a few minor spacing issues are
fixed.
The patch has been tested on Power 10 with no regressions. Please let
me know if the patch is acceptable for mainline. Thanks.

--------------------------------------------------
rs6000, fix vec_replace_unaligned builtin arguments
The first argument of the vec_replace_unaligned builtin should always be
unsinged char, as specified in gcc/doc/extend.texi.
This patch fixes the buitin definitions and updates the testcases to use
the correct arguments.
gcc/ChangeLog:
* config/rs6000/rs6000-overload.def (__builtin_vec_replace_un):
Fix first argument type.
gcc/testsuite/ChangeLog:
* gcc.target/powerpc/ver-replace-word-runnable.c
(vec_replace_unaligned) Fix first argument type.
(vresult_uchar): Fix expected results.
(vec_replace_unaligned): Update for loop to check uchar results.
Remove extra spaces in if statements.
Insert missing spaces in for statements.
(dg-final): Update expected instruction counts.
