Subject: * gdbarch.sh: Emit a definition and declaration for gdbarch_free,
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=023b6accf5e98d813d06359468308d1d9114e575;p=pf3gnuchains%2Fsourceware.git

* gdbarch.sh: Emit a definition and declaration for gdbarch_free,
a companion to gdbarch_alloc, which allows a gdbarch init function
to free partially-built gdbarch structures.
* gdbarch.c, gdbarch.h: Regenerated.
