[LLVMdev] Fixed-point arithmetic

[Sergey Yakoushkin]

Hi all,

Were there any further discussion or progress with the fixed point support
(ISO/IEC TR 18037) in the meantime?
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1275.pdf

Particularly:
1) named address space type qualifiers (can be nested)
2) fract/accum data types
3) sat (saturation) type specifier

Regards,
Sergey Yakushkin
