Add attribute(warn_unused_result) This adds a compiler check that the function result is used by the caller and enables it by default for all cairo_private functions and for public API that returns a cairo_status_t. It has been discussed that to extend the warnings to all functions, a new function type could been introduced to cover static functions: cairo_static. This has not been done at the present time in order to minimise the churn and focus on the more common errors. In order to reduce the warning spew generated by gcc for invalid use of this attribute, -Wno-attributes is added to CFLAGS. This has the unfortunate side-effect of masking future warnings for all attributes - be warned! 2007-04-08 20:50:08 +01:00			`-Wnested-externs -fno-strict-aliasing \`

Port MMX code from xserver to pixman. Add an fbpict.c ported from the latest in xserver/fb, including hooks to the MMX code where appropriate. This replaces the old ic.c file. Replaced by fbpict.c. Move some X server macros from fbpict.c up into icint.h to keep the diff small. Add fbmmx and fbpict.c, remove ic.c. Add a check for the MMX intrinsics. gcc >= 3.4 is required. 2005-08-16 16:50:25 +00:00			`dnl ===========================================================================`
