[PATCH 6/8] Make expr_range_in_bb stmt based rather than block based.

First step in moving gori_compute to range_query is to standardize its queries to be stmt based rather than block based. gori_compute works from the bottom of the block back towards the top, so it always has a stmt available for a range_of_expr query, there is no need to use a non-standard entr

[PATCH 8/8] Remove the logical stmt cache for now.

We added the logical stmt depth limit back in January I think, and the logical stmt cache is not currently in use.   This patch removes that code so it doesn't have too be maintained thru these changes. Bootstraps on x86_64-pc-linux-gnu with no regressions.  Pushed. Andrew >From a6e94287d3152

[PATCH 7/8] Adjust fur_source internal api to use gori_compute not, ranger_cache.

I introduced fur_source  a week ago or so to act as the source for operands of fold_stmt.. ie, it encapsulated a range_query source to get operands for the arguments of a stmt when fold_stmt was invoked. One of the API points was an internal ranger version which contains a reference to a range

Re: [PATCH] libgccjit: Handle truncation and extension for casts [PR 95498]

I updated the patch according to the comments by Tom Tromey. There's one question left about your question regarding C_MAYBE_CONST_EXPR, David: I am not sure if we can get a C_MAYBE_CONST_EXPR from libgccjit, and it indeed seems like it's only created in c-family. However, we do use it in libgccj

Re: [PATCH] libgccjit: add some reflection functions in the jit C api

@David: PING As far as I know, the only remaining question is about using `ssize_t` for the return type of some functions. Here's why I use this type: That seemed off to return NULL for the functions returning a size_t to indicate an error. So I changed it to return -1 (and return type to ssize_

Hi, This is the updated version of patch to deal with the bwaves_r degradation due to vector construction fed by strided loads. As Richi's comments [1], this follows the similar idea to over price the vector construction fed by VMAT_ELEMENTWISE or VMAT_STRIDED_SLP. Instead of adding the extra co
