annotate gen/asmstmt.cpp @ 1101:8bf8b058944a
Clean up asm code a bit.
- Use vector instead of Array, reducing allocations.
- Use vectors instead of deques since we only push_back and index.
- Remove redundant typedefs of iterators.
- Comment out unused variable (used only in commented-out GDC code).
- A few whitespace changes.

[svn r377] The previous check was too strict, it completely disallowed gotos within finally blocks. This reenables them as long as they don't cross a finally boundary.

Implemented proper support for naked asm using llvm module level asm. Still not 100% complete, but already 1000 times better that what we had before. Don's BignumX86 implementation from Tango (when turned into a standalone unittest) seems to fully work with no changes, and great performance :)
