*	Remove open Locations.	Bernhard Schommer	2017-02-06	1	-6/+5
\| \| \| \| \|	Locations are only used in two functions and can be referenced there directly.
*	Deactivate warning 27 and added back removed code.	Bernhard Schommer	2016-03-15	1	-4/+4
\| \| \| \| \| \|	The code was mostly there for documentation effort. So warning 27 is deactivated again. Bug 18349
*	Code cleanup.	Bernhard Schommer	2016-03-10	1	-7/+5
\| \| \| \| \| \|	Removed some unused variables, functions etc. and resolved some problems which occur if all warnings except 3,4,9 and 29 are active. Bug 18394.
*	Updated PR by removing whitespaces. Bug 17450.	Bernhard Schommer	2015-10-20	1	-2/+2

*	Refactoring of builtins and annotations in the back-end.	Xavier Leroy	2015-08-21	1	-4/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Before, the back-end languages had distinct instructions - Iannot for annotations, taking structured expressions (annot_arg) as arguments, and producing no results' - Ibuiltin for other builtins, using simple pseudoregs/locations/registers as arguments and results. This branch enriches Ibuiltin instructions so that they take structured expressions (builtin_arg and builtin_res) as arguments and results. This way, - Annotations fit the general pattern of builtin functions, so Iannot instructions are removed. - EF_vload_global and EF_vstore_global become useless, as the same optimization can be achieved by EF_vload/vstore taking a structured argument of the "address of global" kind. - Better code can be generated for builtin_memcpy between stack locations, or volatile accesses to stack locations. Finally, this commit also introduces a new kind of external function, EF_debug, which is like EF_annot but produces no observable events. It will be used later to transport debug info through the back-end, without preventing optimizations.
*	Missing case for the new 'annot' instruction.	Xavier Leroy	2015-04-06	1	-0/+3

*	Merge of "newspilling" branch:	xleroy	2014-07-23	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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

*	Merge of the float32 branch:	xleroy	2013-05-19	1	-1/+5
\| \| \| \| \| \| \| \|	- added RTL type "Tsingle" - ABI-compatible passing of single-precision floats on ARM and x86 git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2260 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Big merge of the newregalloc-int64 branch. Lots of changes in two directions:	xleroy	2013-04-20	1	-0/+147
	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
