2019-07-10	use the correct attributes for ___errno_location	Samuel Holland	-0/+3
	In the public header, __errno_location is declared with the "const" attribute, conditional on __GNUC__. Ensure that its internal alias has the same attributes. Maintainer's note: This change also fixes a regression in quality of code generation -- multiple references to errno in a single function started generating multiple calls again -- introduced by commit e13063aad7aee341d278d2a879a76ec7b59b2ad8.
2018-09-14	add hidden version of &errno accessor function	Rich Felker	-0/+11
	this significantly improves codegen in functions that need to access errno but otherwise have no need for a GOT pointer. we could probably improve it much more by including an inline version of the &errno accessor function, but that depends on having the definitions of struct __pthread and __pthread_self(), which at present would expose a lot more than is appropriate. moving them to a small tls.h later might make this more reasonable.
