Chris Lattner fdfe370406 Output a contorted sequence of instructions to make sure that we don't access 
off the bottom of the stack.  This fixes PR#41

Chris Lattner 97c7a8ed1a Disable the leaf function optimization, which is apparently not legal on 
X86/linux.  :(  The problem is that a signal delivered while the function
is executing could clobber the functions stack.  This is a partial fix
for PR41.

Chris Lattner b4778c73c9 Do not move variable sized allocations to the top of the caller, which might 
break dominance relationships, and is otherwise bad.  This fixes bug:
Inline/2003-10-13-AllocaDominanceProblem.ll.  This also fixes miscompilation
of 3 176.gcc source files (reload1.c, global.c, flow.c)

John Criswell 3104d83bdb Added a link to the main page for LLVM. 
Made the "Submitting a Bug" reference point to the web site, as we want people
using the latest and greatest bug reporting.
Fixed the indentation by assuming that tabs are 8 characters or less.

jello statistic for this (just divide #-bytes-of-code-emitted by 4).

Chris Lattner 951e7329e8 Use external df iterators to avoid revisiting blocks in functions with 
multiple setjmp calls.

Chris Lattner f5d946eced Make use of "external" depth-first iterators to avoid revisiting nodes 
multiple times.  This reduces the time to construct post-dominance sets a LOT.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.

 2003-10-13 16:36:06 +00:00
Chris Lattner 514e18c061 add support for "external" depth first iterators, which store the 'visited' set 
outside of the iterator itself.

the FAQ (FAQ.html).

John Criswell 8af732029a Fequently Asked Questions about LLVM. Mainly focuses on build problems, but 
anything FAQ'ish should go here if it's not heavily documented elsewhere (like
the README.txt file or the Getting Started Guide).

Chris Lattner 97b07c2096 Extricate the "reverse" support from the depth-first iterator. This is really 
a crappy form of post-order traversal which really does not belong here.  While
we are at it, improve documentation and use a vector instead of a stack.

This improves the post dominator analysis pass by ~5%, and probably also helps
other passes as well.

Chris Lattner ab16a659d7 * Remove extraneous #includes 
* Fix a nasty initializer ordering bug.  Any only-CFG passes which registered
  themselves before the CFGOnlyAnalysis vector initialized got forgotten and
  thus got invalidated and recomputed.

In particular, in my compiled version of gccas, the Loop information pass was
being recomputed unnecessarily.

Chris Lattner 56b8526083 Checkin an improvement contributed by Bill: 
Only transform call sites in a setjmp'ing function which are reachable from
the setjmp.  If the call dominates the setjmp (for example), the called
function cannot longjmp to the setjmp.

This dramatically reduces the number of invoke instructions created in some
large testcases.

Chris Lattner c4622a6955 Add support to the loop canonicalization pass to make it transform loops to 
have a SINGLE backedge.  This is useful to, for example, the -indvars pass.

This implements testcase LoopSimplify/single-backedge.ll and closes PR#34
