*	Protect against redefinition of the __i64_xxx helper library functions.	Xavier Leroy	2015-01-20	1	-87/+90
\| \| \| \| \| \| \| \| \| \|	This is achieved by declaring these functions in C2C.ml, then re-checking their declarations in the global environment during the Selection pass. In passing, the "hf" parameter for SelectLong functions was removed and replaced by fixed identifiers corresponding to the actual names of the helper functions.
*	Merge of "newspilling" branch:	xleroy	2014-07-23	1	-0/+28
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- Support single-precision floats as first-class values - Introduce chunks Many32, Many64 and types Tany32, Tany64 to support saving and restoring registers without knowing the exact types (int/single/float) of their contents, just their sizes. - Memory model: generalize the opaque encoding of pointers to apply to any value, not just pointers, if chunks Many32/Many64 are selected. - More properties of FP arithmetic proved. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2537 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Constprop: use "not" for "xorimm(-1)"; optimize == 1 and != 0 comparisons ↵	xleroy	2014-04-09	1	-16/+4

*	Treat casts int64 -> float32 as primitive operations instead of two	xleroy	2013-07-03	1	-0/+24
\| \| \| \| \| \| \| \|	casts int64 -> float64 -> float32. The latter causes double rounding errors. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2290 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

*	Big merge of the newregalloc-int64 branch. Lots of changes in two directions:	xleroy	2013-04-20	1	-0/+1063
	1- new register allocator (+ live range splitting, spilling&reloading, etc) based on a posteriori validation using the Rideau-Leroy algorithm 2- support for 64-bit integer arithmetic (type "long long"). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2200 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
