[SystemZ] Improve AsmParser handling of invalid instructions

Previously, an invalid instruction like:

foo     %r1, %r0

would generate the rather odd error message:

....: error: unknown token in expression
foo     %r1, %r0
^

We now get the more informative:

....: error: invalid instruction
foo     %r1, %r0
^

The same would happen if an address were used where a register was expected.
We now get "invalid operand for instruction" instead.

[SystemZ] Improve AsmParser register parsing

The idea is to make sure that:

(1) "register expected" is restricted to cases where ParseRegister()
    is called and the token obviously isn't a register.

(2) "invalid register" is restricted to cases where a register-like "%..."
    sequence is found, but the "..." makes no sense.

(3) the generic "invalid operand for instruction" is used in cases where
    the wrong register type is used (GPR instead of FPR, etc.).

(4) the new "invalid register pair" is used if the register has the right type,
    but is not a valid register pair.

Testing of (1)-(3) is now restricted to regs-bad.s.  It uses a representative
instruction for each register class to make sure that only registers from
that class are accepted.

(4) is tested by both regs-bad.s (which checks all invalid register pairs)
and insn-bad.s (which tests one invalid pair for each instruction that
requires a pair).

While there, I changed "Number" to "Num" for consistency with the
operand class.

11 years agoMC: Disassembled CFG reconstruction.
Ahmed Bougacha [Fri, 24 May 2013 01:07:04 +0000 (01:07 +0000)]
MC: Disassembled CFG reconstruction.

This patch builds on some existing code to do CFG reconstruction from
a disassembled binary:
- MCModule represents the binary, and has a list of MCAtoms.
- MCAtom represents either disassembled instructions (MCTextAtom), or
  contiguous data (MCDataAtom), and covers a specific range of addresses.
- MCBasicBlock and MCFunction form the reconstructed CFG. An MCBB is
  backed by an MCTextAtom, and has the usual successors/predecessors.
- MCObjectDisassembler creates a module from an ObjectFile using a
  disassembler. It first builds an atom for each section. It can also
  construct the CFG, and this splits the text atoms into basic blocks.

MCModule and MCAtom were only sketched out; MCFunction and MCBB were
implemented under the experimental "-cfg" llvm-objdump -macho option.
This cleans them up for further use; llvm-objdump -d -cfg now generates
graphviz files for each function found in the binary.

In the future, MCObjectDisassembler may be the right place to do
"intelligent" disassembly: for example, handling constant islands is just
a matter of splitting the atom, using information that may be available
in the ObjectFile. Also, better initial atom formation than just using
sections is possible using symbols (and things like Mach-O's
function_starts load command).

This brings two minor regressions in llvm-objdump -macho -cfg:
- The printing of a relocation's referenced symbol.
- An annotation on loop BBs, i.e., which are their own successor.

Relocation printing is replaced by the MCSymbolizer; the basic CFG
annotation will be superseded by more related functionality.

11 years agoAdd MCSymbolizer for symbolic/annotated disassembly.
Ahmed Bougacha [Fri, 24 May 2013 00:39:57 +0000 (00:39 +0000)]
Add MCSymbolizer for symbolic/annotated disassembly.

This is a basic first step towards symbolization of disassembled
instructions. This used to be done using externally provided (C API)
callbacks. This patch introduces:
- the MCSymbolizer class, that mimics the same functions that were used
  in the X86 and ARM disassemblers to symbolize immediate operands and
  to annotate loads based off PC (for things like c string literals).
- the MCExternalSymbolizer class, which implements the old C API.
- the MCRelocationInfo class, which provides a way for targets to
  translate relocations (either object::RelocationRef, or disassembler
  C API VariantKinds) to MCExprs.
- the MCObjectSymbolizer class, which does symbolization using what it
  finds in an object::ObjectFile. This makes simple symbolization (with
  no fancy relocation stuff) work for all object formats!
- x86-64 Mach-O and ELF MCRelocationInfos.
- A basic ARM Mach-O MCRelocationInfo, that provides just enough to
  support the C API VariantKinds.

Most of what works in otool (the only user of the old symbolization API
that I know of) for x86-64 symbolic disassembly (-tvV) works, namely:
- symbol references: call _foo; jmp 15 <_foo+50>
- relocations:       call _foo-_bar; call _foo-4
- __cf?string:       leaq 193(%rip), %rax ## literal pool for "hello"
Stub support is the main missing part (because libObject doesn't know,
among other things, about mach-o indirect symbols).

As for the MCSymbolizer API, instead of relying on the disassemblers
to call the tryAdding* methods, maybe this could be done automagically
using InstrInfo? For instance, even though PC-relative LEAs are used
to get the address of string literals in a typical Mach-O file, a MOV
would be used in an ELF file. And right now, the explicit symbolization
only recognizes PC-relative LEAs. InstrInfo should have already have
most of what is needed to know what to symbolize, so this can
definitely be improved.

I'd also like to remove object::RelocationRef::getValueString (it seems
only used by relocation printing in objdump), as simply printing the
created MCExpr is definitely enough (and cleaner than string concats).

[PowerPC] Clean up generation of ha16() / lo16() markers

When targeting the Darwin assembler, we need to generate markers ha16() and
lo16() to designate the high and low parts of a (symbolic) immediate.  This
is necessary not just for plain symbols, but also for certain symbolic
expression, typically along the lines of ha16(A - B).  The latter doesn't
work when simply using VariantKind flags on the symbol reference.
This is why the current back-end uses hacks (explicitly called out as such
via multiple FIXMEs) in the symbolLo/symbolHi print methods.

This patch uses target-defined MCExpr codes to represent the Darwin
ha16/lo16 constructs, following along the lines of the equivalent solution
used by the ARM back end to handle their :upper16: / :lower16: markers.
This allows us to get rid of special handling both in the symbolLo/symbolHi
print method and in the common code MCExpr::print routine.  Instead, the
ha16 / lo16 markers are printed simply in a custom print routine for the
target MCExpr types.  (As a result, the symbolLo/symbolHi print methods
can now replaced by a single printS16ImmOperand routine that also handles
symbolic operands.)

The patch also provides a EvaluateAsRelocatableImpl routine to handle
ha16/lo16 constructs.  This is not actually used at the moment by any
in-tree code, but is provided as it makes merging into David Fang's
out-of-tree Mach-O object writer simpler.

Since there is no longer any need to treat VK_PPC_GAS_HA16 and
VK_PPC_DARWIN_HA16 differently, they are merged into a single
VK_PPC_ADDR16_HA (and likewise for the _LO16 types).

Bill Schmidt [Wed, 22 May 2013 20:45:11 +0000 (20:45 +0000)]
Recognize ValueType operands in source patterns for fast-isel.

Currently the fast-isel table generator recognizes registers, register
classes, and immediates for source pattern operands.  ValueType
operands are not recognized.  This is not a problem for existing
targets with fast-isel support, but will not work for targets like
PowerPC and SPARC that use types in source patterns.

The proposed patch allows ValueType operands and treats them in the
same manner as register classes.  There is no convenient way to map
from a ValueType to a register class, but there's no need to do so.
The table generator already requires that all types in the source
pattern be identical, and we know the register class of the output
operand already.  So we just assign that register class to any
ValueType operands we encounter.

No functional effect on existing targets.  Testing deferred until the
PowerPC target implements fast-isel.

Change some PowerPC PatLeaf definitions to ImmLeaf for fast-isel.

Using PatLeaf rather than ImmLeaf when defining immediate predicates
prevents simple patterns using those predicates from being recognized
for fast instruction selection.  This patch replaces the immSExt16
PatLeaf predicate with two ImmLeaf predicates, imm32SExt16 and
imm64SExt16, allowing a few more patterns to be recognized (ADDI,
ADDIC, MULLI, ADDI8, and ADDIC8).  Using the new predicates does not
help for LI, LI8, SUBFIC, and SUBFIC8 because these are rejected for
other reasons, but I see no reason to retain the PatLeaf predicate.

[SystemZ] Fix thinko in long branch pass

The original version of the pass could underestimate the length of a backward
branch in cases like:

    alignment to N bytes or more
    ...
    relaxable branch A

 foo: (aligned to M<N bytes)

 bar: (aligned to N bytes)

    relaxable branch B to foo

We don't add any misalignment gap for "bar" because N bytes of alignment
had already been reached earlier in the function.  In this case, assuming
that A is relaxed can push "foo" closer to "bar", and make B appear to be
in range.  Similar problems can occur for forward branches.

I don't think it's possible to create blocks with mixed alignments as
things stand, not least because we haven't yet defined getPrefLoopAlignment()

this yet.
