Hi, The former patch adds isfinite optab for __builtin_isfinite. https://gcc.gnu.org/pipermail/gcc-patches/2024-April/649339.html Thus the builtin might not be folded at front end. The range op for isfinite is needed for value range analysis. This patch adds them. Bootstrapped and tested

The problem is `!a?b:c` pattern will create a COND_EXPR with an 1bit signed integer which breaks patterns like `a?~t:t`. This rejects when we have a signed operand for both patterns. Note for GCC 15, I am going to look at the canonicalization of `a?~t:t` where t was a constant since I think
