[PATCH v2 0/4] system/memory: Clarify unaligned load/store API

Posted by Philippe Mathieu-Daudé 4 weeks, 1 day ago

I have been confused by the load/store 'host endian' API
for years: this is just about unaligned loads/stores.
Rename to clarify.

v2:
- No "memory_" since it's for host pointers and not
  guest memory addresses (Paolo)
- Fix regexps

Philippe Mathieu-Daudé (4):
  docs/devel/loads-stores: Clarify regexp are POSIX basic ones
  docs/devel/loads-stores: Fix ld/stn_*_p() regexp
  system/memory: Extract 'qemu/ldst_unaligned.h' header
  system/memory: Rename unaligned load/store API
