D attribute support has been updated to have a baseline parity with the
LLVM D compiler's own `ldc.attributes'.
The handler that extracts GCC attributes from a list of UDAs has been
improved to take care of some mistakes that could have been warnings.
UDAs attached to field variables are also now processed for any GCC
attributes attached to them.
The following new attributes have been added to the D front-end:
- @attribute("alloc_size")
- @attribute("used")
- @attribute("optimize")
- @attribute("restrict")
- @attribute("cold")
- @attribute("noplt")
- @attribute("target_clones")
- @attribute("no_icf")
- @attribute("noipa")
- @attribute("symver")
With convenience aliases in a new `gcc.attributes' module to match
the same naming convention as `ldc.attributes':
- @allocSize()
- @assumeUsed
- @fastmath
- @naked
- @restrict
- @cold
- @noplt
- @optStrategy()
- @polly
- @section()
- @target()
- @weak
The old gcc.attribute module has been deprecated, along with the removal
of the following attribute handlers:
- @attribute("alias"): Has been superseded by `pragma(mangle)'.
- @attribute("forceinline"): Renamed to always_inline.
