Constants

PINNED_REG

The pinned register on this architecture. It must be the same as Spidermonkey’s HeapReg, as found in this file. https://searchfox.org/mozilla-central/source/js/src/jit/arm64/Assembler-arm64.h#103

Functions

fp_reg

Get a reference to the frame pointer (x29).

link_reg

Get a reference to the link register (x30).

pinned_reg

Get a reference to the pinned register (x21).

pretty_print_ireg

pretty_print_reg

pretty_print_reg_sized

pretty_print_vreg_element

pretty_print_vreg_scalar

pretty_print_vreg_vector

show_ireg_sized

If ireg denotes an Int-classed reg, make a best-effort attempt to show its name at the 32-bit size.

show_vreg_element

Show an indexed vector element.

show_vreg_scalar

Show a vector register used in a scalar context.

show_vreg_vector

Show a vector register.

spilltmp_reg

Get a reference to the first temporary, sometimes “spill temporary”, register. This register is used to compute the address of a spill slot when a direct offset addressing mode from FP is not sufficient (+/- 2^11 words). We exclude this register from regalloc and reserve it for this purpose for simplicity; otherwise we need a multi-stage analysis where we first determine how many spill slots we have, then perhaps remove the reg from the pool and recompute regalloc.

stack_reg

Get a reference to the stack-pointer register.

tmp2_reg

Get a reference to the second temp register. We need this in some edge cases where we need both the spilltmp and another temporary.

vreg

Get a reference to a V-register (vector/FP register).

writable_fp_reg

Get a writable reference to the frame pointer.

writable_link_reg

Get a writable reference to the link register.

writable_spilltmp_reg

Get a writable reference to the spilltmp reg.

writable_stack_reg

Get a writable reference to the stack-pointer register.

writable_tmp2_reg

Get a writable reference to the tmp2 reg.

writable_vreg

Get a writable reference to a V-register.

writable_xreg

Get a writable reference to an X-register.

writable_zero_reg

Get a writable reference to the zero-register (this discards a result).

xreg

Get a reference to an X-register (integer register). Do not use this for xsp / xzr; we have two special registers for those.

zero_reg

Get a reference to the zero-register.
