[PATCH v3 00/13] Remove GCC < 4.8 checks
Posted by marcandre.lureau@redhat.com 3 years, 4 months ago 
From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

Since commit efc6c07 ("configure: Add a test for the minimum compiler version"),
QEMU explicitely depends on GCC >= 4.8.

v3:
 - drop first patch replacing QEMU_GNUC_PREREQ with G_GNUC_CHECK_VERSION
 - add last patch to remove QEMU_GNUC_PREREQ
 - tweak commit messages to replace clang 3.8 with clang 3.4
 - fix some extra coding style
 - collect r-b/a-b tags

v2:
 - include reviewed Philippe earlier series
 - drop problematic patch to replace GCC_FMT_ATTR, but tweak the check to be clang
 - replace QEMU_GNUC_PREREQ with G_GNUC_CHECK_VERSION
 - split changes
 - add patches to drop __GNUC__ checks (clang advertizes itself as 4.2.1, unless
   -fgnuc-version=0)

Marc-André Lureau (11):
  compiler.h: remove GCC < 3 __builtin_expect fallback
  qemu-plugin.h: remove GCC < 4
  tests: remove GCC < 4 fallbacks
  virtiofsd: replace _Static_assert with QEMU_BUILD_BUG_ON
  compiler.h: explicit case for Clang printf attribute
  audio: remove GNUC & MSVC check
  poison: remove GNUC check
  xen: remove GNUC check
  compiler: remove GNUC check
  linux-user: remove GNUC check
  compiler.h: remove QEMU_GNUC_PREREQ

Philippe Mathieu-Daudé (2):
  qemu/atomic: Drop special case for unsupported compiler
  accel/tcg: Remove special case for GCC < 4.6
