Jonas Maebe	ec0d98156c	* use maytrap instead of strict FP exception behaviour in LLVM, so constant ... propagation is still allowed git-svn-id: trunk@43832 -	2020-01-01 19:19:08 +00:00
Jonas Maebe	1f5efe2a95	* support for constrained sitofp/uitofp with (the upcoming) LLVM 10.0 ... (fixes most of test/units/math/troundm, although there's still an LLVM optimizer/code generation bug that breaks some qword -> double conversions) git-svn-id: trunk@43829 -	2019-12-31 18:05:54 +00:00
Jonas Maebe	9bd33f7a45	+ support for LLVM metadata constant string parameters ... o they are implemented as a new metadata register class, whereby the subregister indicates the metadata type (currently always a string) and the superregister is an index in the metadata array (which contains the strings). LLVM metadata can only be passed as parameters to intrinsics in bitcode, so moves of metadata into other registers triggers internal errors and when moving them into parameters, we replace the parameter's register with the metadata register (and look up the corresponding string when writing out the bitcode) git-svn-id: trunk@43816 -	2019-12-30 15:04:57 +00:00
Jonas Maebe	3fa6838815	* basic llvm metadata support ... git-svn-id: branches/debug_eh@41978 -	2019-05-02 19:45:26 +00:00
