Argyrios Kyrtzidis 58c65410ac Support implicit includes when generating a PCH and allow the user to pass a -include on the command line following the PCH include.

Kevin Enderby e46564a4a8 This is the last major patch to implement support for the .loc directive
and output the dwarf line number tables.  This contains the code to emit and
encode the dwarf line tables from the previously gathered information in the
MCLineSection objects.  This contains all the details to encode the line and
address deltas into the dwarf line table.

To do this an MCDwarfLineAddrFragment has been added.

Also this moves the interface code out of Mach-O streamer into
MCDwarf so it should be useable by other object file formats.

There is now one call to be made from an MCObjectStreamer
EmitInstruction() method:
   MCLineEntry::Make(this, getCurrentSection());
to create a line entry after each instruction is assembled.

And one call call to be made from an MCObjectStreamer Finish() method:
   MCDwarfFileTable::Emit(this, DwarfLineSection);
when getContext().hasDwarfFiles() is true and is passed a object file specific
MCSection where to emit the dwarf file and the line tables.

This appears to now be correct for 32-bit targets, at least x86.  But the
relocation entries for 64-bit Darwin needs some further work which is next
up to work on.  So for now the 64-bit Mach-O target does not output the
dwarf file and line tables.

Kevin Enderby dce906c77f Changes EvaluateAsAbsolute() to return the "current value" of the expression
if we are given a Layout object, even in cases when the value is not fixed.
This will be needed by the final patch for the dwarf .loc support to size a
new MCDwarf fragment needed to build and emit dwarf line number tables.

reduces the amount of malloc calls and may reduce memory overhead.

Rafael Espindola 70d6e0e0ff Correctly produce R_X86_64_32 or R_X86_64_32S.
With this patch in

movq    $foo, foo(%rip)
foo:
.long   foo

We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the
second one.

Rafael Espindola 2ebaee9c75 Make it possible for the MCObjectWriter to decide if a given fixup is fully
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

Jim Grosbach 4a57b76eea Let a target specify whether it wants an assembly printer to be the MC version
or not. TableGen needs to generate the printInstruction() function as taking
an MCInstr* or a MachineInstr*, depending. Default to the old non-MC
version so that everything not yet using MC continues to just work without
fidding.

Tom Care ea7c48ccf7 Updated scan-build:
- Idempotent operations are on by default, to match --analyze in the driver.
- Integrated stats calculation based on parsing warnings emitted with the -analyzer-stats flag. The new -stats flag enables this.
- New -maxloop flag to pass down a maxloop value to the analyzer.

Evan Cheng 2fb20b1d37 ARM instruction itinerary fixes:
1. Cortex-a9 8-bit and 16-bit loads / stores AGU cycles are 1 cycle longer than 32-bit ones.
2. Cortex-a9 is out-of-order so model all read cycles as cycle 1.
3. Lots of other random fixes for A8 and A9.

2010-09-30 01:06:29 +00:00
Ted Kremenek e18dd0a84e Change CheckerVisitor so that [Pre,Post]VisitCallExpr only handles CallExprs for simple C functions, not
all CallExprs (including CXXMemberCallExpr, etc.).  Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.

Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.

Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.

Tom Care 2f0419e1f8 AnalyzerStatsChecker improvements:
