| | | | | | | | | | | allow the built-in operations to be redefined, at least not without excessive force). Instead, just disable LLVM's support for atomic operations for now. Nothing in either clang or the tablegen tools currently depends on it. This still allows users of head built before r198344 to upgrade to top-of-head seamlessly.

| | | | | | | | | | | to be gcc's default before r198344, calls to atomic builtins will not be expanded inline. Instead, they will be generated as calls to external functions (e.g. __sync_fetch_and_add_N), leading to linking errors later on. Put in a seatbelt that disables use of atomic builtins in libstdc++ and llvm, when tuning specifically for the real i386 CPU. This does not protect against all possible issues, but it is better than nothing.

* On amd64, change clang's default triple to 'x86_64-unknown-freebsd9.0',dim2011-05-221-1/+1
| | | | | | | | | | | | | | | | similar to what we do for binutils. When clang's default triple starts with 'amd64-', it does not pass a proper -target-cpu option to its first stage. This can lead to problems, for example when structs are memcpy'd, and clang erroneously assumes they are 16-byte aligned. It will then use the 'movaps' SSE instruction to implement the copy, which results in a bus error if the struct is really 8-byte aligned. I encountered this issue when gcc's /usr/libexec/cc1 started crashing with SIGBUS, after rebuilding world with clang ToT, but it also affects the version of clang that we have in the tree. We were just lucky until now, apparently. :)

* Update llvm/clang to trunk r126547.dim2011-02-273-3/+4
| | | | | | | | | | | | | | There are several bugfixes in this update, but the most important one is to ensure __start_ and __stop_ symbols for linker sets and kernel module metadata are always emitted in object files: http://llvm.org/bugs/show_bug.cgi?id=9292 Before this fix, if you compiled kernel modules with clang, they would not be properly processed by kldxref, and if they had any dependencies, the kernel would fail to load those. Another problem occurred when attempting to mount a tmpfs filesystem, which would result in 'operation not supported by device'.

* Upgrade our Clang in base to r108428.ed2010-07-2055-408/+973
| | | | | | | | | This commit merges the latest LLVM sources from the vendor space. It also updates the build glue to match the new sources. Clang's version number is changed to match LLVM's, which means /usr/include/clang/2.0 has been renamed to /usr/include/clang/2.8. Obtained from: projects/clangbsd

* Disable usage of posix_spawn() inside LLVM.ed2010-06-132-2/+2
| | | | | | | | | Even though it's nice to use posix_spawn() instead of manually using fork()/exec(), it's better to disable this. FreeBSD 7 doesn't support this interface. When enabled, we can't build tblgen, which prevents us from building FreeBSD 9 on 7. Tested by: raj
* Do the branding right this time.ed2010-06-121-1/+2
| | | | | | | | | I've looked at other places in the source tree where CLANG_VENDOR is used and I suspect it might not be safe to use newlines here. CLANG_VENDOR should just be defined to "FreeBSD ", just like the latest Clang preview in OS X uses "Apple ". Properly use SVN_REVISION to define it to the imported revision of Clang. I do want to have a date in there, so slightly modify the code to support CLANG_VENDOR_SUFFIX.
* Disable usage of __DATE__.ed2010-06-101-1/+1
| | | | | This ensures that the Clang binary doesn't change checksums every time it's built.
