New features
- New command-line options for ARM:
-midiv
enables the generation of hardware integer division instructions
for targets that only optionally support them.-finline-runtime
triggers inline expansion
of all library functions for 64-bit arithmetic.
- Added minimal syntactic support for type
_Float16.
- C99 array declarator syntax involving
static is now accepted by the parser,
even though this annotation is ignored during compilation.
Improved diagnostics
The diagnostics have been improved for:
- Flexible array members in structs containing zero-width bit-fields
- Arrays of unions containing flexible array members
Other improvements
- Various improvements to:
- Code generation of 64-bit arithmetic for 32-bit backends
- Dead code elimination for 64-bit operations
- Value analysis for unsigned comparisons
- Improved error message for bit-field of type
_Bool
with size 2...8.
Fixes
$NNN identifiers are now escaped in x86 and ARM assembly code.- Fixed assertion failure in spilling for ARM functions with a large number of float arguments.
Valex
- Support for marking input sections as removed by the linker.
- Upon encountering an error, Valex now carries on with the rest of the checks.
