Issue ID: 15933
Summary: GDC support for core.cpuid
Product: D
Version: D2
Hardware: x86_64
OS: All
Status: NEW
Severity: minor
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
GDC does not implement DMD style inline assembly, but offers another inline
assembly mechanism called extended assembler where the asm block is a template
filled out by the compiler and passed to an external assembler executable that
understands either AT&T or Intel style on x86.
In the simplest form core.cpuid needs a few versioned asm blocks for GDC that
duplicate what the DMD asm blocks do.
Another idea is to replace the accessor properties with direct access to the
global constants (mmx, hasPopcnt, etc.) to work around GDC's inability to
inline across modules.
