9 years ago[X86] When optimizing for minsize, use POP for small post-call stack clean-up
Michael Kuperstein [Tue, 11 Aug 2015 08:48:48 +0000 (08:48 +0000)]
[X86] When optimizing for minsize, use POP for small post-call stack clean-up

When optimizing for size, replace "addl $4, %esp" and "addl $8, %esp"
following a call by one or two pops, respectively. We don't try to do it in
general, but only when the stack adjustment immediately follows a call - which
is the most common case.

That allows taking a short-cut when trying to find a free register to pop into,
instead of a full-blown liveness check. If the adjustment immediately follows a
call, then every register the call clobbers but doesn't define should be dead at
that point, and can be used.

x86: Emit LAHF/SAHF instead of PUSHF/POPF

NaCl's sandbox doesn't allow PUSHF/POPF out of security concerns (priviledged emulators have forgotten to mask system bits in the past, and EFLAGS's DF bit is a constant source of hilarity). Commit r220529 fixed PR20376 by saving cmpxchg's flags result using EFLAGS, this commit now generated LAHF/SAHF instead, for all of x86 (not just NaCl) because it leads to an overall performance gain over PUSHF/POPF.

As with the previous patch this code generation is pretty bad because it occurs very later, after register allocation, and in many cases it rematerializes flags which were already available (e.g. already in a register through SETE). Fortunately it's somewhat rare that this code needs to fire.

James Y Knight [Mon, 10 Aug 2015 19:11:39 +0000 (19:11 +0000)]
[Sparc] Implement i64 load/store support for 32-bit sparc.

The LDD/STD instructions can load/store a 64bit quantity from/to
memory to/from a consecutive even/odd pair of (32-bit) registers. They
are part of SparcV8, and also present in SparcV9. (Although deprecated
there, as you can store 64bits in one register).

As recommended on llvmdev in the thread "How to enable use of 64bit
load/store for 32bit architecture" from Apr 2015, I've modeled the
64-bit load/store operations as working on a v2i32 type, rather than
making i64 a legal type, but with few legal operations. The latter
does not (currently) work, as there is much code in llvm which assumes
that if i64 is legal, operations like "add" will actually work on it.

The same assumption does not hold for v2i32 -- for vector types, it is
workable to support only load/store, and expand everything else.

This patch:
- Adds a new register class, IntPair, for even/odd pairs of registers.

- Modifies the list of reserved registers, the stack spilling code,
  and register copying code to support the IntPair register class.

- Adds support in AsmParser. (note that in asm text, you write the
  name of the first register of the pair only. So the parser has to
  morph the single register into the equivalent paired register).

- Adds the new instructions themselves (LDD/STD/LDDA/STDA).

- Hooks up the instructions and registers as a vector type v2i32. Adds
  custom legalizer to transform i64 load/stores into v2i32 load/stores
  and bitcasts, so that the new instructions can actually be
  generated, and marks all operations other than load/store on v2i32
  as needing to be expanded.

- Copies the unfortunate SelectInlineAsm hack from ARMISelDAGToDAG.
  This hack undoes the transformation of i64 operands into two
  arbitrarily-allocated separate i32 registers in
  SelectionDAGBuilder. and instead passes them in a single
  IntPair. (Arbitrarily allocated registers are not useful, asm code
  expects to be receiving a pair, which can be passed to ldd/std.)

Also adds a bunch of test cases covering all the bugs I've added along
the way.

split is no longer rematerializable. This is because the isRematerializable
