[PATCH] Fortran: checking and simplification of RESHAPE intrinsic [PR103794]

Dear all, checking and simplification of the RESHAPE intrinsic could fail in various ways for sufficiently complicated arguments, like array constructors. Debugging revealed that in these cases we determined that the array arguments were constant but we did not properly simplify and expand the co

Re: [PATCH 7/7] Expand directly for single bit test

Hi, Andrew Thanks for this series of patches to improve do_store_flag. Unfortunately this specific patch in the series has caused a bootstrap failure on powerpc-aix. I bisected this failure to this specific patch. Note that I am building as 32 bit, so this could be a specific issue about bit siz
