[Qemu-devel] [PATCH v3 0/6] Remove libqemu related stuff from QEMU source tree

[Qemu-devel] [PATCH v3 0/6] Remove libqemu related stuff from QEMU source tree

[Chen Wei-Ren (陳韋任)]

From: Chen Wei-Ren <chenwj@iis.sinica.edu.tw>

  According to [1], libqemu is not available anymore. Remove libqemu
related stuff from QEMU source tree.

[1] http://www.mail-archive.com/address@hidden/msg49809.html

v2:
 - Remove entry "qruncom.c" from "3 Regression Tests" in qemu-tech.texi.
 - Undo the deletion of common-obj-y. Only remove libqemu_common.a from
   the comment.

v3:
 - Change tests/Makefile first before removing tests/qruncom.c.
 - Only remove out-of-date comment about libqemu.a from Makefile.target,
   leave manually inserted dependencie alone.

Chen Wei-Ren (6):
  tests/Makefile: Remove qruncom target
  tests/qruncom.c: Remove libqemu.a example
  qemu-tech.texi: Remove libqemu related stuff from the document
  Makefile.target: Remove out of date comment
  Makefile.objs: Remove libqemu_common.a from the comment
  LICENSE: There is no libqemu.a anymore
