Module `dmd.backend.cgreg`

Compiler implementation of the D programming language.

Functions

Name	Description
`cgreg_benefit(s, reg, retsym)`	Determine 'benefit' of assigning symbol s to register reg. Benefit is roughly the number of clocks saved. A negative value means that s cannot or should not be assigned to reg.
`cgreg_benefit(s, reg, retsym)`	Determine 'benefit' of assigning symbol s to register reg. Benefit is roughly the number of clocks saved. A negative value means that s cannot or should not be assigned to reg.
`cgreg_gotoepilog(b, s)`	Determine if block gets symbol loaded by predecessor epilog (1), or by prolog (0).
`cgreg_gotoepilog(b, s)`	Determine if block gets symbol loaded by predecessor epilog (1), or by prolog (0).
`cgreg_init()`
`cgreg_init()`
`cgreg_map(s, regmsw, reglsw)`	Map symbol s into registers [NOREG,reglsw] or [regmsw, reglsw].
`cgreg_map(s, regmsw, reglsw)`	Map symbol s into registers [NOREG,reglsw] or [regmsw, reglsw].
`cgreg_reset()`
`cgreg_reset()`
`cgreg_spillreg_epilog(b, s, cdbstore, cdbload)`	Determine block epilog code - it's either assignments to register, or storing register back in memory.
`cgreg_spillreg_epilog(b, s, cdbstore, cdbload)`	Determine block epilog code - it's either assignments to register, or storing register back in memory.
`cgreg_spillreg_prolog(b, s, cdbstore, cdbload)`	Determine block prolog code for `s` - it's either assignments to register, or storing register back in memory.
`cgreg_spillreg_prolog(b, s, cdbstore, cdbload)`	Determine block prolog code for `s` - it's either assignments to register, or storing register back in memory.
`cgreg_term()`
`cgreg_term()`
`cgreg_unregister(conflict)`	The register variables in this mask can not be in registers. "Unregister" them.
`cgreg_unregister(conflict)`	The register variables in this mask can not be in registers. "Unregister" them.
`cgreg_used(bi, used)`	Registers used in block bi.
`cgreg_used(bi, used)`	Registers used in block bi.
