* Libdw: Add libdw-based stack unwindingBen Gamari2015-10-171-0/+5
| | | | | | | | | | | | | | | | | | | | | This adds basic support to the RTS for DWARF-assisted unwinding of the Haskell and C stack via libdw. This only adds the infrastructure; consumers of this functionality will be introduced in future diffs. Currently we are carrying the initial register collection code in Libdw.c but this will eventually make its way upstream to libdw.

* workaround Solaris 11 GNU C CPP issue by using GNU C 3.4 as CPPKarel Gardas2014-08-171-58/+2
| | | | | | | | | | | | | | | | | | | | | | | Summary: Solaris 11 distributed GNU C 4.5.x is configured in a way that its CPP is not working well while invoked from GHC. GHC runs it with -x assembler-with-cpp and in this particular configuration GNU C CPP does not provide any line-markers so GHC's output of errors or warnings is confusing since it points to preprocessed file in /tmp and not to the original Haskell file. Fortunately old GNU C 3.4.x is still provided by the OS and when installed it'll be used automatically as GHC CPP which is whole logic of this patch. So although we use modern GCC as a C compiler and assembler we use old GCC as a C preprocessor.

* Detect linker information at runtime. Fixes Trac #6063Austin Seipp2013-06-161-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we did ./configure time checks to see if 'GNU ld' supported certain options. If it does, we bake those options into the link step. See Trac #5240. Unfortunately, the linker we use at runtime can change for several reasons. One is that the user specifies -pgml 'foo'. The other is if /usr/bin/ld or whatnot changes from when GHC was built. Those options mentioned earlier are specific to GNU ld, but many systems support GNU gold too. This is Trac #6063. So we need to check at runtime what linker we're using. This is actually a little bit complicated because we normally use the C compiler as our linker. Windows and OS X are also special here. Finally, this patch also unconditionally gives '--hash-size=31' and '--reduce-memory-overheads' to the system linker if it's GNU ld. These options have been supported for 8+ years from what I can see, and there are probably a lot of other reasons why GHC would not work with such an ancient binutils, all things considered. See Note [Run-time linker info] in SysTools for details. There are plenty of comments as well in the surrounding code. Signed-off-by: Austin Seipp <aseipp@pobox.com>
* Tweak the bindist comparison toolIan Lynagh2013-04-202-1/+6
| | | | | | It now just warns about files it doesn't recognise, rather than giving an error. This means that random text files etc in the same directory as the bindists don't make it fall over.

* Build the dynamic way by default on Linux/amd64Ian Lynagh2012-10-031-1/+1
| | | | | | | | | | | | | This required various build system changes to get the build to go through. In the inplace shell wrappers, we set LD_LIBRARY_PATH to allow programs to find their libraries. In the future, we might change the inplace tree to be the same shape as an installed tree instead. However, this would mean changing the way we do installation, as currently we use cabal's installation methods to install the libraries, but that only works if the libraries are under libraries/foo/dist-install/build/..., rather than in inplace/lib/...

* Use /usr/bin/gcc when making the OS X installerIan Lynagh2012-01-111-1/+1
| | | | | | | On XCode 4.1, we use /usr/bin/gcc-4.2 as it makes better code than /usr/bin/gcc for us. However, gcc-4.2 doesn't exist in XCode 4.2, so we need to use /usr/bin/gcc there. As the installer can be used on either, we make it always use /usr/bin/gcc.
