Subject [Harmony Wiki] Update of "Jitrino OPT/regalloc" by Mikhail Fursov
Date Mon, 12 May 2008 09:25:34 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Harmony Wiki" for change notification.

The following page has been changed by Mikhail Fursov:

New page:
''' 'regalloc' ''' - a global register allocator
This transformation attempts to assign register for any operand (found in LIR) that can be
allocated in register.[[BR]]
A set of registers available for allocation is specified by input arguments. [[BR]]
The operands that cannot be placed to register are ignored.[[BR]]
This allocator should be called for each set of the registers available (GPReg, XMM, FP) independently.
It is not guaranteed that all operands which can be assigned to registers will be assigned.

Therefore, the companion transformation [:Jitrino_OPT/spillgen: spillgen] must be used after
this pass.
