[PATCH] c++: __builtin_shufflevector with value-dep expr [PR105353]

Here we issue an error from c_build_shufflevector while parsing a template because it got a TEMPLATE_PARM_INDEX, but this function expects INTEGER_CSTs (except the first two arguments). It checks if any of the arguments are type-dependent, if so, we leave the processing for later, but it should

Whoops, this patch is identical to https://gcc.gnu.org/pipermail/gcc-patches/2022-April/593502.html that I sent about an hour ago, sorry for the noise. On Fri, Apr 22, 2022 at 2:33 PM Patrick Palka wrote: > > Here ever since r11-6483-ge2e2f3f2c9400f we're rejecting and crashing > (respectively)

[PATCH] c++: crash with requires-expr and -Wsequence-point [PR105304]

Here we're crashing from verify_sequence_points for this requires-expr condition because it contains a templated CAST_EXPR with empty operand, and verify_tree doesn't ignore this empty operand only because the manual tail recursion that it perform for unary expression trees skips the NULL test.

[PATCH] rtlanal: Fix up replace_rtx [PR105333]

Hi! The following testcase FAILs, because replace_rtx replaces a REG with CONST_WIDE_INT inside of a SUBREG, which is an invalid transformation because a SUBREG relies on SUBREG_REG having non-VOIDmode but CONST_WIDE_INT has VOIDmode. replace_rtx already has code to deal with it, but it was
