Benjamin Kramer 12af4285d1 Emit the LLVM<->DWARF register mapping as a sorted table and use binary search to do the lookup. 
This also avoids emitting the information twice, which led to code bloat. On i386-linux-Release+Asserts
with all targets built this change shaves a whopping 1.3 MB off clang. The number is probably exaggerated
by recent inliner changes but the methods were already enormous with the old inline cost computation.

The DWARF reg -> LLVM reg mapping doesn't seem to have holes in it, so it could be a simple lookup table.
I didn't implement that optimization yet to avoid potentially changing functionality.

There is still some duplication both in tablegen and the generated code that should be cleaned up eventually.

libcxx It appears that the standard accidentally removed the default constructor for error_category. I'm putting it back in. This fixes http://llvm.org/bugs/show_bug.cgi?id=12321. 2012-03-21 16:18:57 +00:00
libcxxabi I would really like to write the handlers in terms of C++11 atomics. This would give us the best performance, portablity, and safety tradeoff. Unfortunately I can not yet do that. So I've put the desired code in comments, and reverted the handler getters to the slower but safer legacy atomic intrinsics. 2012-03-19 16:56:51 +00:00
