John McCall	757c0ae304	Track whether a type is POD and whether it uses inline or allocated ... storage in a flags word in the value witness table. Pack the alignment into only 16 bits of this word. Optimize tuple value witnesses based on whether they're POD and inline. Swift SVN r5138	2013-05-10 06:16:33 +00:00
John McCall	d8cdb0160f	Switch IR-generation to generally traffic in alignment ... masks rather than raw alignments. Swift SVN r5136	2013-05-10 06:16:28 +00:00
Joe Groff	b818405034	Replace direct use of [[clang::fallthrough]] with a macro. ... Add a SWIFT_FALLTHROUGH macro that expands to [[clang::fallthrough]] for Clang and nothing for other compilers. No functionality change. Swift SVN r5043	2013-05-05 18:54:03 +00:00
Joe Groff	08b6f87524	Add 'typeof' to value witness tables. ... To be able to get the dynamic type of a generic value, the 'typeof' operation needs to be part of the value witness for the type. Add 'typeof' to the value witness table layout, and in the runtime, provide standard typeof witnesses for static, Swift class, and ObjC class values. Swift SVN r5013	2013-05-01 18:49:25 +00:00
Joe Groff	0566088bf2	Move name mangling into SIL. ... Sever the last load-bearing link between SILFunction and SILConstant by naming SILFunctions with their mangled symbol names. Move the core of the mangler up to SIL, and teach SILGen how to use it to mangle a SILConstant. Swift SVN r4964	2013-04-28 03:32:41 +00:00
