Subject: [patch i386]: Set for method-functions default calling-convention to thiscall for 32-bit msabi

Hello,

this patch sets for c++ methods, which are not stdarg ones, the
default calling-convention to thiscall for ms_abi 32-bit, as vendor
specific compiler does.

ChangeLog

2011-04-01  Kai Tietz

	* i386.c (ix86_is_msabi_thiscall): New helper function.
	(ix86_comp_type_attributes): Handle thiscall for method-functions
	special.
	(init_cumulative_args): Likewise.
	(find_drap_reg): Likewise.
	(ix86_static_chain): Likewise.
	(x86_this_parameter): Likewise.
	(x86_output_mi_thunk): Likewise.


Tested for i686-w64-mingw32 (some parts of the g++ testsuite are still
running). Regression tested for i686-pc-cygwin, x86_64-pc-linux-gnu.
Ok for apply?

Regards,
Kai
