Re: Re: [PATCH] RISC-V: Add testcases for VSETVL PASS

This is another issue and I have no idea. I think palmer or kito may have know how to solve it. It seems this patch https://gcc.gnu.org/pipermail/gcc-patches/2022-December/609045.html fixed previous issue which is more important. I think it's time to merge it. juzhe.zh...@rivai.ai From:

Tested by building a toolchain and compiling gnumach for x86_64 [1]. This is the basic version without unwind support which I think is only required to implement exceptions. [1] https://github.com/flavioc/cross-hurd/blob/master/bootstrap-kernel.sh. --- gcc/config.gcc | 5 -

Hi Gaius, I’m finding it hard to figure out how the configuration is supposed to work for cross compilers (and more so for Canadian/native crosses). Apologies if this is already answered in other review (but maybe some notes would help in that case). questions in-line, thanks Iain > On 26 De

[RFC] Introduce -finline-memset-loops

try_store_by_multiple_pieces was added not long ago, enabling variable-sized memset to be expanded inline when the worst-case in-range constant length would, using conditional blocks with powers of two to cover all possibilities of length and alignment. This patch extends the memset expansion to

[00/13] check hash table counts

While looking into another issue that corrupted hash tables, I added code to check consistency of element counts, and hit numerous issues that were concerning, of three kinds: insertion of entries that seem empty, dangling insertions, and lookups during insertions. These problems may all have th

[01/13] scoped tables: insert before further lookups

Avoid hash table lookups between requesting an insert and storing the inserted value in avail_exprs_stack. Lookups before the insert is completed could fail to find double-hashed elements. Regstrapped on x86_64-linux-gnu. Ok to install? for gcc/ChangeLog * tree-ssa-scopedtables.cc

cxx_eval_call_expression requests an INSERT even in cases when it would later decide not to insert. This could break double-hashing chains. Arrange for it to use NO_INSERT when the insertion would not be completed. Regstrapped on x86_64-linux-gnu. Ok to install? for gcc/cp/ChangeLog
