It would have been better had the fmdrr been scheduled +before the call and place the result in a callee-save DPR register. The two +mov ops would not have been necessary. + +//===---------------------------------------------------------------------===// + +Calling convention related stuff: + +* gcc's parameter passing implementation is terrible and we suffer as a result: + +e.g. +struct s { + double d1; + int s1; +}; + +void foo(struct s S) { + printf("%g, %d\n", S.d1, S.s1); +} + +'S' is passed via registers r0, r1, r2. But gcc stores them to the stack, and +then reload them to r1, r2, and r3 before issuing the call (r0 contains the +address of the format string): + + stmfd sp!, {r7, lr} + add r7, sp, #0 + sub sp, sp, #12 + stmia sp, {r0, r1, r2} + ldmia sp, {r1-r2} + ldr r0, L5 + ldr r3, [sp, #8] +L2: + add r0, pc, r0 + bl L_printf$stub + +Instead of a stmia, ldmia, and a ldr, wouldn't it be better to do three moves? + +* Return an aggregate type is even worse: + +e.g. +struct s foo(void) { + struct s S = {1.1, 2}; + return S; +} + + mov ip, r0 + ldr r0, L5 + sub sp, sp, #12 +L2: + add r0, pc, r0 + @ lr needed for prologue + ldmia r0, {r0, r1, r2} + stmia sp, {r0, r1, r2} + stmia ip, {r0, r1, r2} + mov r0, ip + add sp, sp, #12 + bx lr + +r0 (and later ip) is the hidden parameter from caller to store the value in. The +first ldmia loads the constants into r0, r1, r2. The last stmia stores r0, r1, +r2 into the address passed in. However, there is one additional stmia that +stores r0, r1, and r2 to some stack location. The store is dead. + +The llvm-gcc generated code looks like this: + +csretcc void %foo(%struct.s* %agg.result) { +entry: + %S = alloca %struct.s, align 4 ; <%struct.s*> [#uses=1] + %memtmp = alloca %struct.s ; <%struct.s*> [#uses=1] + cast %struct.s* %S to sbyte* ; <sbyte*>:0 [#uses=2] + call void %llvm.memcpy.i32( sbyte* %0, sbyte* cast ({ double, int }* %C.0.904 to sbyte*), uint 12, uint 4 ) + cast %struct.s* %agg.result to sbyte* ; <sbyte*>:1 [#uses=2] + call void %llvm.memcpy.i32( sbyte* %1, sbyte* %0, uint 12, uint 0 ) + cast %struct.s* %memtmp to sbyte* ; <sbyte*>:2 [#uses=1] + call void %llvm.memcpy.i32( sbyte* %2, sbyte* %1, uint 12, uint 0 ) + ret void +} + +llc ends up issuing two memcpy's (the first memcpy becomes 3 loads from +constantpool). Perhaps we should 1) fix llvm-gcc so the memcpy is translated +into a number of load and stores, or 2) custom lower memcpy (of small size) to +be ldmia / stmia. I think option 2 is better but the current register +allocator cannot allocate a chunk of registers at a time. + +A feasible temporary solution is to use specific physical registers at the +lowering time for small (<= 4 words?) transfer size. + +* ARM CSRet calling convention requires the hidden argument to be returned by +the callee. + +//===---------------------------------------------------------------------===// + +We can definitely do a better job on BB placements to eliminate some branches. +It's very common to see llvm generated assembly code that looks like this: + +LBB3: + ... +LBB4: +... + beq LBB3 + b LBB2 + +If BB4 is the only predecessor of BB3, then we can emit BB3 after BB4. We can +then eliminate beq and and turn the unconditional branch to LBB2 to a bne. + +See McCat/18-imp/ComputeBoundingBoxes for an example. + +//===---------------------------------------------------------------------===// + +Pre-/post- indexed load / stores: + +1) We should not make the pre/post- indexed load/store transform if the base ptr +is guaranteed to be live beyond the load/store. This can happen if the base +ptr is live out of the block we are performing the optimization. e.g. + +mov r1, r2 +ldr r3, [r1], #4 +... + +vs. + +ldr r3, [r2] +add r1, r2, #4 +... + +In most cases, this is just a wasted optimization. However, sometimes it can +negatively impact the performance because two-address code is more restrictive +when it comes to scheduling. + +Unfortunately, liveout information is currently unavailable during DAG combine +time. + +2) Consider spliting a indexed load / store into a pair of add/sub + load/store + to solve #1 (in TwoAddressInstructionPass.cpp). + +3) Enhance LSR to generate more opportunities for indexed ops. + +4) Once we added support for multiple result patterns, write indexed loads + patterns instead of C++ instruction selection code. + +5) Use VLDM / VSTM to emulate indexed FP load / store. + +//===---------------------------------------------------------------------===// + +Implement support for some more tricky ways to materialize immediates.
