[Qemu-devel] [PATCH v3 0/5] Fix strncpy() warnings for GCC8 new -Wstringop-truncation

[Philippe Mathieu-Daudé]

GCC 8 new warning prevents builds to success since quite some time.
First report on the mailing list is in July 2018:
https://lists.gnu.org/archive/html/qemu-devel/2018-07/msg03723.html

Various intents has been sent to fix this:
- Incorrectly using g_strlcpy()
  https://lists.gnu.org/archive/html/qemu-devel/2018-08/msg03705.html
  https://lists.gnu.org/archive/html/qemu-devel/2018-08/msg03706.html
- Using assert() and strpadcpy()
  https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg03938.html
- Use #pragma GCC diagnostic ignored "-Wstringop-truncation"
  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04261.html
- adding an inline wrapper with said pragma in there
  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04261.html
- -Wno-stringop-truncation is the makefile
  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04261.html
- Use the 'nonstring' attribute
  https://lists.gnu.org/archive/html/qemu-devel/2018-12/msg04493.html

This series add the QEMU_NONSTRING definition and use it.

Regards,

Phil.
