# Syllabus:
#
# Examples of some roles, types, and widths:
# U:G:32 => use of the low 32 bits of a general-purpose register or value
# D:G:32 => def of the low 32 bits of a general-purpose register or value
# UD:G:32 => use and def of the low 32 bits of a general-purpose register or value
# U:G:64 => use of the low 64 bits of a general-purpose register or value
# ZD:G:32 => def of all bits of a general-purpose register, where all but the low 32 bits are guaranteed to be zeroed.
# UA:G:Ptr => UseAddr (see comment in Arg.h)
# U:F:32 => use of a float register or value
# U:F:64 => use of a double register or value
# D:F:32 => def of a float register or value
# UD:F:32 => use and def of a float register or value
# S:F:32 => scratch float register.
#
# Argument kinds:
# Tmp => temporary or register
# Imm => 32-bit immediate int
# BigImm => TrustedImm64
# Addr => address as temporary/register+offset
# Index => BaseIndex address
# Abs => AbsoluteAddress
#
# The parser views these things as keywords, and understands that they fall into two distinct classes
# of things. So, although this file uses a particular indentation style, none of the whitespace or
# even newlines are meaningful to the parser. For example, you could write:
#
# Foo42 U:G:32, UD:F:32 Imm, Tmp Addr, Tmp
#
# And the parser would know that this is the same as:
#
# Foo42 U:G:32, UD:F:32
#     Imm, Tmp
#     Addr, Tmp
#
# I.e. a two-form instruction that uses a GPR or an int immediate and uses+defs a float register.
#
# Any opcode or opcode form can be preceded with an architecture list, which restricts the opcode to the
# union of those architectures. For example, if this is the only overload of the opcode, then it makes the
# opcode only available on x86_64:
#
# x86_64: Fuzz UD:G:64, D:G:64
#     Tmp, Tmp
#     Tmp, Addr
#
# But this only restricts the two-operand form, the other form is allowed on all architectures:
#
# x86_64: Fuzz UD:G:64, D:G:64
#     Tmp, Tmp
#     Tmp, Addr
# Fuzz UD:G:Ptr, D:G:Ptr, U:F:Ptr
#     Tmp, Tmp, Tmp
#     Tmp, Addr, Tmp
#
# And you can also restrict individual forms:
#
# Thingy UD:G:32, D:G:32
#     Tmp, Tmp
#     arm64: Tmp, Addr
#
# Additionally, you can have an intersection between the architectures of the opcode overload and the
# form. In this example, the version that takes an address is only available on armv7 while the other
# versions are available on armv7 or x86_64:
#
# x86_64 armv7: Buzz U:G:32, UD:F:32
#     Tmp, Tmp
#     Imm, Tmp
#     armv7: Addr, Tmp
#
# Finally, you can specify architectures using helpful architecture groups. Here are all of the
# architecture keywords that we support:
#
# x86: means x86-32 or x86-64.
# x86_32: means just x86-32.
# x86_64: means just x86-64.
# arm: means armv7 or arm64.
# armv7: means just armv7.
# arm64: means just arm64.
# 32: means x86-32 or armv7.
# 64: means x86-64 or arm64.

# Note that the opcodes here have a leading capital (Add32) but must correspond to MacroAssembler
# API that has a leading lower-case (add32).

# Note that Move operates over the full register size, which is either 32-bit or 64-bit depending on

# Move64 instruction. OTOH, our MacroAssemblers already have this notion of "move()" that basically
# means movePtr.
