From-SVN: r86190

Hot/cold partitioning update patch.

Hot/cold partitioning update patch.  The problems that this patch
attemptd to address/fix are:

- Fix places where adding in_unlikely_executed_text to the enum data
  type "in_section"  threw off switch case statements.
- Make it work correctly (by turning it off) for functions where user
  specifies "__attribute__ section"
- Make it work correctly (by turning it off) for linkonce sections
- Make it work correctly with -ffunction-sections flag
- Make it output correct cold section labels
- Undo some changes to original assembly code generation
- Turn off hot/cold partitioning in the presence of DWARF debugging (for
  the moment)
- Turn off hot/cold partitioning for architectures that do not support
  named sections
- Use variables rather than constants for cold section labels and names (to
  work correctly with -ffunction-sections, among other things)

baseline_symbols.txt: Update to 3.4.0.

2004-08-17  Paolo Carlini  <pcarlini@suse.de>

* config/abi/ia64-linux-gnu/baseline_symbols.txt: Update to 3.4.0.

From-SVN: r86142

Add -mdynamic-no-pic to compile flags for gcc.  On Mac OS X and Darwin,

the compiler generates position-independent-code by default.  This allows
an object file to be used for a dylib or executable without any thought
on the developer's part, but generates less-efficient code.  Setting this
flag on gcc speeds compiles by 3-5%.
        * config/rs6000/x-darwin: Add -mdynamic-no-pic to gcc build flags.
