[PATCH] D35115: X86 Asm should produce error messages instead of assertions when it's possible

[Andrew V. Tischenko via Phabricator via llvm-commits]

avt77 updated this revision to Diff 107675.
avt77 retitled this revision from "Clang's assembler crashes if Scale in lea is negative (pr33661)" to "X86 Asm should produce error messages instead of assertions when it's possible".
avt77 added a comment.

This patch replaces assertions with normal diagnostic when it's possible. Now we see normal error messages instead of compiler crashes. It should close PR33861, PR33862 and PR33661. In addition the patch prepares tests for https://reviews.llvm.org/D35621.
