2011-12-06rt: Various tweaks to make __morestack unwinding work on linuxBrian Anderson-0/+7
When unwinding through __morestack the stack limit in the TLS is invalidated and must be reset. Instead of actually landing at __morestack we're just going to make all our Rust landing pads call upcall_reset_stack_limit, which will find the stack segment that corresponds to the current stack pointer and put the limit in the TLS. Also massively expand the stack segment red zone to make more room for the dynamic linker. Will fix in the future.
2011-12-06Make valgrind usage more consistent and less error prone.Austin Seipp-3/+1
I was still having issues with the build system somehow getting confused as to which set of valgrind headers to use when compiling rt. This commit moves all the valgrind headers into their own directory under rt and makes the usage more consistent. The compiler is now passed the -DNVALGRIND flag when valgrind is not installed, as opposed to passing -DHAVE_VALGRIND. We also pass -I src/rt to the compiler when building rt so you can more easily import what you want. I also cleaned up some erroneous #includes along the way. It should be safe to always just import the local valgrind headers and use them without question. NVALGRIND turns the operations to no-ops when it is active, and the build and tests run cleanly with or without.

The motivation here is that the bottom of each stack needs to contain a C++ try/catch block so that we can unwind. This is already the case for main, but not spawned tasks. Issue #236
