Dan Gohman	9e4ab7dc86	Rename CallConv::Native to CallConv::SystemV. (#291 ) To keep cross-compiling straightforward, Cretonne shouldn't have any behavior that depends on the host. This renames the "Native" calling convention to "SystemV", which has a defined meaning for each target, so that it's clear that the calling convention doesn't change depending on what host Cretonne is running on.	2018-03-30 12:32:14 -07:00
Jakob Stoklund Olesen	91b1566aca	Use "test regalloc" for the register allocator tests. These tests were only using "test compile" because it doesn't require any filecheck directives to be present, so just stop requiring filecheck directives for "test regalloc" and other filecheck-based test drivers.	2017-10-25 18:31:14 -07:00
Jakob Stoklund Olesen	e8ecf1f809	Add a FixedTied constraint kind for operand constraints. Fixes #175. The Intel division instructions have fixed input operands that are clobbered by fixed output operands, so the value passed as an input will be clobbered just like a tied operand. The FixedTied operand constraint is used to indicate a fixed input operand that has a corresponding output operand with the same fixed register. Teach the spiller to teach a FixedTied operand the same as a Tied operand constraint and make sure that the input value is killed by the instruction.	2017-10-25 11:22:20 -07:00

Rename CallConv::Native to CallConv::SystemV. (#291 )

To keep cross-compiling straightforward, Cretonne shouldn't have any
behavior that depends on the host. This renames the "Native" calling
convention to "SystemV", which has a defined meaning for each target,
so that it's clear that the calling convention doesn't change
depending on what host Cretonne is running on.

Add a FixedTied constraint kind for operand constraints.

Fixes #175.

The Intel division instructions have fixed input operands that are
clobbered by fixed output operands, so the value passed as an input will
be clobbered just like a tied operand.

The FixedTied operand constraint is used to indicate a fixed input
operand that has a corresponding output operand with the same fixed
register.

Teach the spiller to teach a FixedTied operand the same as a Tied
operand constraint and make sure that the input value is killed by the
instruction.
