*	Merge of "newspilling" branch:	xleroy	2014-07-23	1	-0/+12
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	Add option -Os to optimize for code size rather than for execution speed.	xleroy	2014-02-19	1	-16/+29
\| \| \| \| \| \| \| \|	Refactored compilation flags that affect the Coq part (module Compopts). Added support for C99 for loops with declarations. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2410 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Floats.v, Nan.v: hard-wire the general shape of binop_pl, so that no axioms	xleroy	2013-09-14	1	-1/+17

ConstpropOp: optimize 2.0 * x and x * 2.0 into x + x. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2326 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
