@ -241,6 +241,21 @@ Bug fixes:
* The correct libcall is now emitted for converting a float/double to a 32-bit
signed or unsigned integer on RV64 targets lacking the F or D extensions.
Changes to the SystemZ Target
-----------------------------
* Added support for the MemorySanitizer and the LeakSanitizer.
* Added support for the ``-fstack-clash-protection`` command line option.
* Enhanced the assembler parser to allow using `%r0` even in an address
register context, and to allow specifying registers using plain integer
numbers instead of register names everywhere.
* Fixed wrong code generation violating the platform ABI when passing
a C++ class (not struct) type having only a single member of
floating-point type.
* Fixed wrong code generation when using the `vec_store_len_r` or
`vec_load_len_r` intrinsics with an immediate length argument of
16 or larger.
* Miscellaneous codegen enhancements, in particular to improve vector code.
Changes to the X86 Target
