26 ; Try using PQImode again for addresses since C30 only uses
27 ; 24-bit addresses. Ideally GCC would emit different insns
28 ; for QImode and Pmode, whether Pmode was QImode or PQImode.
29 ; For addresses we wouldn't have to have a clobber of the CC
30 ; associated with each insn and we could use MPYI in address
31 ; calculations without having to synthesise a proper 32 bit multiply.

137 ; Note that the 'd', 'f', and 'h' constraints are equivalent.
138 ; The m constraint is equivalent to 'QT<>{}'
140 ; Note we cannot use the 'g' constraint with Pmode (i.e, QImode)
141 ; operations since LEGITIMATE_CONSTANT_P accepts SYMBOL_REF.
142 ; So instead we use 'rIm' for signed operands or 'rLm' for unsigned operands.
144 ; Note that the constraints are used to select the operands
145 ; for a chosen pattern. The constraint that requires the fewest
146 ; instructions to load an operand is chosen.
148 ; Note that the 'r' constraint is mostly only used for src integer register
149 ; operands, while 'c' and 'd' constraints are generally only used for dst
150 ; integer register operands (the 'r' constraint is the union of the 'c' and
151 ; 'd' constraints). When a register satisfying the 'd' constraint
152 ; is used as a dst operand, the CC gets clobbered (except for LDIcond)---but
155 ; The 'f' constraint is only for float register operands---when
156 ; a register satisying the 'f' constraint is used as a dst operand,
157 ; the CC gets clobbered (except for LDFcond).
159 ; The ! in front of the 'b' constaint says to GCC to disparage the
160 ; use of this constraint. The 'b' constraint applies only to the SP.
162 ; Note that we deal with the condition code CC like some of the RISC
163 ; architectures (arm, sh, sparc) where it is stored in a general register,
164 ; in this case the hard register ST (21). Unlike these other architectures
165 ; that do not set the CC with many instructions, the C[34]x architectures
166 ; sets the CC for many instructions when the destination register is
167 ; an extended precision register. While it would have been easier
168 ; to use the generic cc0 register to store the CC, as with most of
169 ; the other ported architectures, this constrains the setting and testing
170 ; of the CC to be consecutive insns. Thus we would reduce the benefit
171 ; of scheduling instructions to avoid pipeline conflicts and filling of
172 ; delayed branch slots.
174 ; Since the C[34]x has many instructions that set the CC, we pay the
175 ; price of having to explicity define which insns clobber the CC
176 ; (rather than using the macro NOTICE_UPDATE_CC).
178 ; Note that many patterns say that the CC is clobbered when in fact
179 ; that it may not be (depending on the destination register).
180 ; We have to cover ourselves if an extended precision register
181 ; is allocated to the destination register.
182 ; Unfortunately, it is not easy to tell GCC that the clobbering of CC
183 ; is register dependent. If we could tolerate the ST register being
184 ; copied about, then we could store the CC in a pseudo register and
185 ; use constructs such as (clobber (match_scratch:CC N "&y,X")) to
186 ; indicate that the 'y' class (ST register) is clobbered for the
187 ; first combination of operands, but not with the second.
188 ; I tried this approach for a while but reload got unhappy since I
189 ; didn't allow it to move the CC around.
191 ; Note that fundamental operations, such as moves, must not clobber the
192 ; CC. Thus movqi choses a move instruction that doesn't clobber the CC.
193 ; If GCC wants to combine a move with a compare, it is smart enough to
194 ; chose the move instruction that sets the CC.
196 ; Unfortunately, the C[34]x instruction set does not have arithmetic or
197 ; logical operations that never touch the CC. We thus have to assume
198 ; that the CC may be clobbered at all times. If we define patterns
199 ; such as addqi without the clobber of CC, then GCC will be forced
200 ; to use registers such as the auxiliary registers which can cause
201 ; horrible pipeline conflicts. The tradeoff is that GCC can't now
202 ; sneak in an add instruction between setting and testing of the CC.
204 ; Most of the C[34]x instructions require operands of the following formats,
205 ; where imm represents an immediate constant, dir a direct memory reference,
206 ; ind an indirect memory reference, and reg a register:
208 ; src2 (op2) src1 (op1) dst (op0)
209 ; imm dir ind reg | imm dir ind reg | reg Notes
210 ;---------------------+----------------------+------
211 ; ILH T Q<> r | - - - 0 | r 2 operand
212 ; - - S<> r | - - S<> r | r
213 ; J - R - | - - R r | r C4x
215 ; Arithmetic operations use the I, J constraints for immediate constants,
216 ; while logical operations use the L, J constraints. Floating point
217 ; operations use the H constraint for immediate constants.
219 ; With most instructions the src2 and src1 operands are commutative
220 ; (except for SUB, SUBR, ANDN). The assembler considers
221 ; ADDI 10, R0, R1 and ADDI R0, 10, R1 to be equivalent.
222 ; We thus match src2 and src1 with the src_operand predicate and
223 ; use valid_operands as the extra constraint to reject invalid
224 ; operand combinations. For example, ADDI @foo, @bar, R0.
226 ; Note that we use the ? modifier so that reload doesn't preferentially
227 ; try the alternative where three registers are acceptable as
228 ; operands (whenever an operand requires reloading). Instead it will try
229 ; the 2 operand form which will produce better code since it won't require
230 ; a new spill register.
232 ; Note that the floating point representation of 0.0 on the C4x
233 ; is 0x80000000 (-2147483648). This value produces an warning
234 ; message on 32-bit machines about the decimal constant being so large
235 ; that it is unsigned.
237 ; With two operand instructions patterns having two sets,
238 ; the compare set must come first to keep the combiner happy.
239 ; While the combiner seems to cope most of the time with the
240 ; compare set coming second, it's best to have it first.
