*	Issue with ignoring the result of non-void builtin functions.	Xavier Leroy	2015-09-15	1	-1/+4
\| \| \| \|	In RTL and beyond, the result of a builtin function that has return type different from "void" must be BR, never BR_none. Otherwise, we get compile-time fatal errors, either in Asmexpand or in Lineartyping.
*	More portable test for fres and fsqrte.	Xavier Leroy	2015-07-08	1	-2/+11
\| \| \| \|	These instructions are approximate and produce different results on different processors. Just check the error bounds specified in the PPC ISA.
*	Rename __builtin_cntlz to __builtin_clz.	xleroy	2014-08-27	1	-1/+1
\| \| \| \| \| \| \|	IA32: add __builtin_clz, __builtin_ctz. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2619 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	- Recognize __builtin_fabs as an operator, not just a builtin,	xleroy	2013-11-06	1	-0/+3
\| \| \| \| \| \| \| \| \|	enabling more aggressive optimizations. - Less aggressive CSE for EF_builtin builtins, causes problems for __builtin_write{16,32}_reversed. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2363 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Add __builtin_bswap16 and __builtin_bswap32 to all ports.	xleroy	2013-04-20	1	-0/+48
	Remove __builtin_{read,write}_reversed from IA32 and ARM ports. Machregs: tighten destroyed_by_builtin Packedstructs: use bswap if read/write-reversed not available. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2208 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
