Devang Patel abc77347a7 Enable GlobalMerge on darwin. 
llvm-svn: 128183
 2011-03-23 23:34:19 +00:00
Devang Patel a0d73fd65e Disable ARMGlobalMerge on darwin. The debugger is not yet able to extract individual variable's info from merged global.

Bob Wilson 881b45ccdf Change ARMGlobalMerge to keep BSS globals in separate pools. 
This completes the fixes for Radar 8673120.

Bob Wilson 4c8ab19c22 Fix ARMGlobalMerge pass to check if globals are entirely within range. 
It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

Bob Wilson 59182fb4b5 Change the symbol for merged globals from "merged" to "_MergedGlobals". 
This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

Bob Wilson f796d4b469 Fix the ARMGlobalMerge pass to look at variable sizes instead of pointer sizes. 
It was mistakenly looking at the pointer type when checking for the size of
global variables.  This is a partial fix for Radar 8673120.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Anton Korobeynikov 6bcea068db Currently EH lowering code expects typeinfo to be global only. 
This assumption is not satisfied due to global mergeing.
Workaround the issue by temporary disablinge mergeing of const globals.
Also, ignore LLVM "special" globals. This fixes PR7716
