[AArch64][SVE] Improve diagnostics for vectors with incorrect element-size. For regular SVE vector operands, this patch introduces a more sensible diagnostic when the vector has a wrong suffix (e.g. z0.s vs z0.b). For example: add z0.s, z1.s, z2.b -> invalid element width ^_____^ mismatch For the vector-with-shift/extend (e.g. z0.s, uxtw #2) this patch takes a slightly different approach and instead returns a 'invalid operand' if the element size is not as expected. This is because the diagnostics are more specificied to suggest using the right shift/extend suffix. This is a trade-off not to introduce more operand classes and still provide useful diagnostics for LD1 and PRF instructions. For example: ld1w z1.s, p0/z, [x0, z0.s] -> invalid shift/extend specified, expected 'z[0..31].s, (uxtw|sxtw)' ld1w z1.d, p0/z, [x0, z0.s] -> invalid operand ^________________^ mismatch For gather prefetches, both 'z0.s' and 'z0.d' would be allowed: prfw #0, p0, [x0, z0.s] -> invalid shift/extend specified, expected 'z[0..31].s, (uxtw|sxtw) #2' prfw #0, p0, [x0, z0.d] -> invalid shift/extend specified, expected 'z[0..31].d, (lsl|uxtw|sxtw) #2' Without this change, the diagnostic would unnecessarily suggest a different element size: prfw #0, p0, [x0, z0.s] -> invalid shift/extend specified, expected 'z[0..31].d, (lsl|uxtw|sxtw) #2' Reviewers: SjoerdMeijer, aemerson, fhahn, samparker, javed.absar Reviewed By: SjoerdMeijer Differential Revision: https://reviews.llvm.org/D46688 llvm-svn: 332483

[AArch64][SVE] Asm: Enable instructions to be prefixed. This patch enables instructions that are destructive on their destination- and first source operand, to be prefixed with a MOVPRFX instruction. This patch also adds a variety of tests: - positive tests for all instructions and forms that accept a movprfx for either or both predicated and unpredicated forms. - negative tests for all instructions and forms that do not accept an unpredicated or predicated movprfx. - negative tests for the diagnostics that get emitted when a MOVPRFX instruction is used incorrectly. This is patch [2/2] in a series to add MOVPRFX instructions: - Patch [1/2]: https://reviews.llvm.org/D49592 - Patch [2/2]: https://reviews.llvm.org/D49593 Reviewers: rengolin, SjoerdMeijer, samparker, fhahn, javed.absar Reviewed By: SjoerdMeijer Differential Revision: https://reviews.llvm.org/D49593 llvm-svn: 338261
