Neuheiten
- Support for link-time optimization with -flto
- The compiler tools now support linking -mfpu=f32 code into -mfpu=f64 projects. Previously, this resulted in a link-time error.
- Security support in linker command files have been enhanced with more options. See the Compiler User's Guide chapter "The Safety and Security Unit" for details.
- New floating point mode: -mfpu=none, which emulates all floating point operations in general-purpose registers. Used to avoid saves/restores of floating-point registers on-entry to an interrupt.
- At -O3, integer division sequences are now emitted inline, rather than called
- Memory operations will more intelligently use the built-in address scaling of offset registers
- General reduction of superfluous or redundant sign and zero extension
- More performant C-library math.h functions via the use of -ffast-math or through intrinsics. See the Compiler User's Guide chapter "Built-In Functions and Intrinsics" for details.
