[IRA] Skip empty register classes in setup_reg_class_relations

Hi, I've been spending some (spare) time trying to get LRA working for the avr target. After making a couple of changes to get libgcc going, I'm now hitting an assert at lra-constraints.cc:4423 for a subarch (avrtiny) that has a couple of regclasses with no available registers. The as

[PATCH] Update array address space in c_build_qualified_type

Hi, When c-typeck.cc:c_build_qualified_type builds an array type from its element type, it does not copy the address space of the element type to the array type itself. This is unlike tree.cc:build_array_type_1, which explicitly does TYPE_ADDR_SPACE (t) = TYPE_ADDR_SPACE (elt_type); Th

[PATCH, PR110086] avr: Fix ICE on optimize attribute

Hi, This patch fixes an ICE when an optimize attribute changes the prevailing optimization level. I found https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105069 describing the same ICE for the sh target, where the fix was to enable save/restore of target specific options modified via TARGET_OPTIMIZA

[Testsuite] Skip -fdelete-null-pointer-check tests if target keeps_null_pointer_checks

Hi, When running regression tests related to https://gcc.gnu.org/pipermail/gcc-patches/2023-April/616772.html, I noticed a bunch of failures because some tests explicitly pass in -fdelete-null-pointer-checks, even if the target is configured to keep them. This patch skips such failing tests by a

[PATCH] avr: Set param_min_pagesize to 0 [PR105523]

Hi, This patch fixes PR 105523 by setting param_min_pagesize to 0 for the avr target. For this target, zero and offsets from zero are perfectly valid addresses, and the default value of param_min_pagesize ends up triggering warnings on valid memory accesses. Ok for trunk and backporting to 13 and
