GCC documentation: info format

2010-04-09 Thread christophe . jarry
Hello, I am currently trying to include GCC documentation into gNewSense distribution, in info format. While most of GNU software documentation is available directly from GNU site in info format (see http://www.gnu.org/manual/manual.html), I'm surprised to see this is not the case for GCC

dragonegg in FSF gcc?

2010-04-09 Thread Jack Howarth
What are the opinions here about merging dragonegg into FSF gcc? It is in the odd position of straddling two projects so perhaps it could reside in both the LLVM and FSF gcc projects with regularly remerging. Certainly it would be an interesting addition to FSF gcc. For instance, without even at

may_be_unaligned_p bug?

2010-04-09 Thread DJ Delorie
In tree-ssa-loop-ivopts.c:may_be_unaligned_p(), we call get_inner_reference to figure out bitpos, but we don't take into account toffset - which may make the reference less aligned than we expect. Is this supposed to be accounted for by STEP ? It doesn't always work with nested arrays - STEP is
