This has been wrong for many years. It was originally 0x000FFFFF and long ago there was discussion about whether GL_ALL_ATTRIB_BITS should include the then-new GL_MULTISAMPLE_BIT bit. Eventually the ARB decided that glPushAttrib(GL_ALL_ATTRIB_BITS) should save all current and future attribute groups (hence ~0). Unfortunately, Mesa's gl.h was never updated.
This was just recently spotted by Eric Anholt and reported as a bug to the ARB. Ian, Jon Leech and I discussed it at the ARB meeting and decided to change Mesa's value to reflect the ARB's decision. --- include/GL/gl.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/GL/gl.h b/include/GL/gl.h index 48343f6..4e2932d 100644 --- a/include/GL/gl.h +++ b/include/GL/gl.h @@ -694,7 +694,7 @@ typedef double GLclampd; /* double precision float in [0,1] */ #define GL_LIST_BIT 0x00020000 #define GL_TEXTURE_BIT 0x00040000 #define GL_SCISSOR_BIT 0x00080000 -#define GL_ALL_ATTRIB_BITS 0x000FFFFF +#define GL_ALL_ATTRIB_BITS 0xFFFFFFFF /* OpenGL 1.1 */ -- 1.7.10.4 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
