Module lower 

Lower the semantic BuildAction IR into concrete command argv for a Dialect.

This is the single point where compile/archive/link intent becomes a real command line. lower() dispatches on the dialect; the GNU/Clang and MSVC spellings live side by side below. The planner, the IR, and the Ninja writer never spell a flag themselves - they call lower() (or compile_argv for the compilation database).

Structs

LoweredAction

A fully-lowered action: the backend artifact the Ninja writer renders.

Enums

LoweredActionKind

Categorization of a lowered action. A closed set; new variants require explicit handling by every backend.

Functions

compile_argv

Build the unwrapped compiler argv for a compile action in dialect - the form recorded in compile_commands.json (no compiler wrapper). lower() prepends the wrapper on top of this for the run command.

lower

Lower one semantic BuildAction for dialect.
