* Makeconfig: Use a space before a newline escapeAlejandro Colomar2023-08-29-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | That space doesn't affect make(1)'s behavior, AFAIK. Be consistent in adding the space, to avoid confusing readers into believing that it has a different meaning. I had to do a lot of tests to convince myself that I didn't change the meaning, and am still not 100% convinced, so we better not confuse others. Here's an experiment to justify this patch: $ cat Makefile A := a B := b C := c D := $(addprefix $(A), start.o S$(B))\ $(C) foo E := $(addprefix $(A), start.o S$(B)) \ $(C) foo F := A\ B $(info $(D)) $(info $(E)) $(info $(F)) $ make astart.o aSb c foo astart.o aSb c foo A B make: *** No targets.

* nscd: Skip unusable entries in first pass in prune_cache (bug 30800)Florian Weimer2023-08-29-14/+11
| | | | | | | | | | | | | | | | | | Previously, if an entry was marked unusable for any reason, but had not timed out yet, the assert would trigger. One way to get into such state is if a data change is detected during re-validation of an entry. This causes the entry to be marked as not usable. If exits nscd soon after that, then the clock jumps backwards, and nscd restarted, the cache re-validation run after startup triggers the removed assert. The change is more complicated than just the removal of the assert because entries marked as not usable should be garbage-collected in the second pass. To make this happen, it is necessary to update some book-keeping data. Reviewed-by: DJ Delorie <dj@redhat.com>

* LoongArch: Add ifunc support for memcmp{aligned, lsx, lasx}dengjianbo2023-08-29-0/+861
| | | | | | | | | | | According to glibc memcmp microbenchmark test results(Add generic memcmp), this implementation have performance improvement except the length is less than 3, details as below: Name Percent of time reduced memcmp-lasx 16%-74% memcmp-lsx 20%-50% memcmp-aligned 5%-20%
* LoongArch: Add ifunc support for memset{aligned, unaligned, lsx, lasx}dengjianbo2023-08-29-0/+688
| | | | | | | | | | | | | | According to glibc memset microbenchmark test results, for LSX and LASX versions, A few cases with length less than 8 experience performace degradation, overall, the LASX version could reduce the runtime about 15% - 75%, LSX version could reduce the runtime about 15%-50%. The unaligned version uses unaligned memmory access to set data which length is less than 64 and make address aligned with 8. For this part, the performace is better than aligned version. Comparing with the generic version, the performance is close when the length is larger than 128. When the length is 8-128, the unaligned version could reduce the runtime about 30%-70%, the aligned version could reduce the runtime about 20%-50%.

| | | | | | | | | According to glibc rawmemchr microbenchmark, A few cases tested with char '\0' experience performance degradation due to the lasx and lsx versions don't handle the '\0' separately. Overall, rawmemchr-lasx implementation could reduce the runtime about 40%-80%, rawmemchr-lsx implementation could reduce the runtime about 40%-66%, rawmemchr-aligned implementation could reduce the runtime about 20%-40%.
