[PATCH 00/12] linux-user: Extract target errno related functions to 'target_errno.h'

[Philippe Mathieu-Daudé]

Hi,

This series extract code related to target errno conversion
(to/from host) into a separate header.

While reviewing I noticed EWOULDBLOCK is defined as EAGAIN
on alpha/hppa/mips targets, these are the first 3 patches.

Then each target errno definitions are extracted to a new
header: 'target_errno_defs.h' (patches 4-9).

Finally we extract the generic target errno functions to the
new 'target_errno.c' file in patches 10-12

Up to here it seems a good refactor.

>From here I'm wondering if we could generate some target specific
library (linux-user-target.fa?) that could be reused by semihosting
code (at least for the Xtensa target). Just an idea...

Philippe Mathieu-Daudé (12):
  linux-user/alpha: Handle TARGET_EWOULDBLOCK as TARGET_EAGAIN
  linux-user/hppa: Handle TARGET_EWOULDBLOCK as TARGET_EAGAIN
  linux-user/mips: Handle TARGET_EWOULDBLOCK as TARGET_EAGAIN
  linux-user/sparc: Rename target_errno.h -> target_errno_defs.h
  linux-user: Extract target errno to 'target_errno_defs.h'
  linux-user/alpha: Remove hardcoded tabs (code style)
  linux-user/alpha: Move errno definitions to 'target_errno_defs.h'
  linux-user/hppa: Move errno definitions to 'target_errno_defs.h'
  linux-user/mips: Move errno definitions to 'target_errno_defs.h'
  linux-user/syscall: Refactor target_to_host_errno_table_init()
  linux-user/syscall: Remove hardcoded tabs (code style)
  linux-user: Extract target errno related functions to 'target_errno.h'
