Rafael Espindola fd9493d74e Odd additional stub framework for the ARM MC ELF emission. 
llc now recognizes the "intent" to support MC/obj emission for ARM, but
given that they are all stubs, it asserts on --filetype=obj --march=arm

Rafael Espindola b142bef30b Represent relocations against local symbols as relocations against the section 
they are in. Both ways should be equivalent, but gas produces relocations
against the section.

 2010-09-16 15:03:59 +00:00
Rafael Espindola d80781b98b Add a InitSections method to the streamer interface. 
The ELF implementation now creates text, data and bss to match the gnu as
behavior.

The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.

A nice benefit is that -n is not required anymore when producing
ELF files.

Rafael Espindola d720670393 The BlockExtractorPass() constructor was not reading the BlockFile and that was 
exactly what bugpoint expected it to do.

There was also only one user of

make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

Rafael Espindola 84ae206c97 Clone and restore the module being reduced in 
ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).

Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.

Rafael Espindola 7e1b566322 Convert the last use of getPhysicalRegisterRegClass and remove it. 
AggressiveAntiDepBreaker should not be using getPhysicalRegisterRegClass. An
instruction might be using a register that can only be replaced with one from
a subclass of getPhysicalRegisterRegClass.

With this patch we use getMinimalPhysRegClass. This is correct, but
conservative. We should check the uses of the register and select the
largest register class that can be used in all of them.

Rafael Espindola cbeb3db8fd Don't use getPhysicalRegisterRegClass in PBQP. The existing checks that the 
physical register can be allocated in the class of the virtual are sufficient.

I think that the test for virtual registers is more strict than it needs to be,
it should be possible to coalesce two virtual registers the class of one
is a subclass of the other.

Rafael Espindola db77609991 Convert uses of getPhysicalRegisterRegClass in VirtRegRewriter.cpp. 
The first one was used just to call isSafeToMoveRegClassDefs. In
general, using a more specific reg class is better, in practice only
x86 implements that method and the results are always the same.

The second one is in FindFreeRegister and is used to check if a register
is in a register class, a much more direct call to contains is better as
it should cover more cases and is faster.

Rafael Espindola cbeeae23c3 Fix va_arg for doubles. With this patch VAARG nodes always contain the 
correct alignment information, which simplifies ExpandRes_VAARG a bit.

The patch introduces a new alignment information to TargetLoweringInfo. This is
needed since the two natural candidates cannot be used:

* The 's' in target data: If this is set to the minimal alignment of any
  argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for
  example.
* The getTransientStackAlignment method. It is possible for an architecture to
  have argument less aligned than what we maintain the stack pointer.

Rafael Espindola 11f403cf2b Add an extra-library-path option to the plugin. This is used to support 
having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.

Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.

Rafael Espindola dd76f18f90 Add a pass-through option to the plugin. The use case for this option is to
