Peter Maydell a976d7642a target/arm: Implement M-profile lazy FP state preservation The M-profile architecture floating point system supports lazy FP state preservation, where FP registers are not pushed to the stack when an exception occurs but are instead only saved if and when the first FP instruction in the exception handler is executed. Implement this in QEMU, corresponding to the check of LSPACT in the pseudocode ExecuteFPCheck(). Backports commit e33cf0f8d8c9998a7616684f9d6aa0d181b88803 from qemu		2019-04-30 11:21:50 -04:00

Clean/simple/lightweight/intuitive architecture-neutral API
Implemented in pure C language, with bindings for Crystal, Clojure, Visual Basic, Perl, Rust, Ruby, Python, Java, .NET, Go, Delphi/Free Pascal and Haskell.
Native support for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed)
High performance via Just-In-Time compilation
Support for fine-grained instrumentation at various levels
Thread-safety by design
Distributed under free software license GPLv2
