[PATCH] path solver: Minimize exported ranges to subsequent blocks.

Currently we have a set of interesting names in the path that we solve for. However, solving *all* of them on exit from each block is unnecessary, even if an edge range is available. We can reduce the queried edges by only solving SSA names from the current block that will be needed in subsequent

[PATCH] libstdc++: Implement std::byteswap for C++23

Hi! This patch attempts to implement P1272R4 (except for the std::bit_cast changes in there which seem quite unrelated to this and will need to be fixed on the compiler side). While at least for GCC __builtin_bswap{16,32,64,128} should work fine in constant expressions, I wonder about other compil

Hi, Profile-report was never properly updated after switch to new profile representation. This patch fixes the way profile mismatches are calculated: we used to collect separately count and freq mismatches, while now we have only counts & probabilities. So we verify - in count: that total count

[PATCH] Fix PR 62157: disclean in libsanitizer not working

From: Andrew Pinski So what is happening is DIST_SUBDIRS contains the conditional directories which is wrong, so we need to force DIST_SUBDIRS to be the same as SUBDIRS as recommened by the automake manual. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. Also now make distcl

[PATCH] Fix PR 19089: Environment variable TMP may yield gcc: abort

From: Andrew Pinski Even though I cannot reproduce the ICE any more, this is still a bug. We check already to see if we can access the directory but never check to see if the path is actually a directory. This adds the check and now we reject the file as not usable as a tmp directory. OK? Boots
