commit 427fe081923a2787e7d5f81cfb8d3c389e29ea6e
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Aug 12 21:28:03 2021 -0400
Move xx* builtins to vsx.md.
I noticed that the xx built-in functions (xxspltiw, xxspltidp, xxsplti32dx,
xxeval, xxblend, and xxpermx) were all defined in altivec.md. However, since
the XX instructions can take both traditional floating point and Altivec
registers, these built-in functions should be in vsx.md.
This patch just moves the insns from altivec.md to vsx.md.
I also moved the VM3 mode iterator and VM3_char mode attribute from altivec.md
to vsx.md, since the only use of these were for the XXBLEND insns.

commit 3ba4bf9635aeeb8edf77f3d10086ddc6abbb4756
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Aug 12 21:57:15 2021 -0400
Move xx* builtins to vsx.md.
I noticed that the xx built-in functions (xxspltiw, xxspltidp, xxsplti32dx,
xxeval, xxblend, and xxpermx) were all defined in altivec.md. However, since
the XX instructions can take both traditional floating point and Altivec
registers, these built-in functions should be in vsx.md.
This patch just moves the insns from altivec.md to vsx.md.
I also moved the VM3 mode iterator and VM3_char mode attribute from altivec.md
to vsx.md, since the only use of these were for the XXBLEND insns.
