* Use an ugly hack to get around bootstrapping problems when buildingdim2013-05-131-0/+5
| | | | | | | | | | | | | | | clang on head between r239347 and r245428. The former revision introduced CLOCK_PROCESS_CPUTIME_ID as a clock id for the clock_gettime() function and friends, but it was only added in <sys/time.h>, not in <time.h>. Any program including <time.h> would therefore not be able to use CLOCK_PROCESS_CPUTIME_ID, even though the value of _POSIX_CPUTIME indicates its existence. The latter revision synchronized the defines again. Work around this problem by defining the id on the command line for the particular .cpp file that needs it. If the id ever changes value, this hack will need to be updated.

* Pull in r170135 from upstream clang trunk:dim2013-02-0264-8/+147
| | | | | | | | | | | | | | | | Dont use/link ARCMT, StaticAnalyzer and Rewriter to clang when the user specifies not to. Dont build ASTMatchers with Rewriter disabled and StaticAnalyzer when it's disabled. Without all those three, the clang binary shrinks (x86_64) from ~36MB to ~32MB (unstripped). To disable these clang components, and get a smaller clang binary built and installed, set WITHOUT_CLANG_FULL in src.conf(5). During the initial stages of buildworld, those extra components are already disabled automatically, to save some build time. MFC after: 1 week

* Add support for bmake. This includes:marcel2012-10-061-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE, there's a bootstrap complication in ths respect. Avoid it. Make the necessary changes to have upgrade_checks work wth bmake anyway. 2. Remove the use of -E. It's not needed in our build because we use ?= for the respective variables, which means that we'll take the environment value (if any) anyway. 3. Properly declare phony targets as phony as bmake is a lot smarter (and thus agressive) about build avoidance. 4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot smarter about build avoidance and should not find files we generate in the source tree. We should not have files in the repository we want to generate, but this is an easier way to cross this hurdle. 5. Have behavior under bmake the same as it is under make with respect to halting when sub-commands fail. Add "set -e" to compound commands so that bmake is informed when sub-commands fail. 6. Make sure crunchgen uses the same make as the rest of the build. This is important when the make utility isn't called make (but bmake for example). 7. While here, add support for using MAKEOBJDIR to set the object tree location. It's the second alternative bmake looks for when determining the actual object directory (= .OBJDIR).

| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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'.
