Bump __FreeBSD_version for the addition of cacoshl, cacosl, casinhl, casinl, catanl, catanhl, sincos, sincosf, and sincosl. MFC r305382 (by bde): Add asm versions of fmod(), fmodf() and fmodl() on amd64. Add asm versions of fmodf() amd fmodl() on i387. fmod is similar to remainder, and the C versions are 3 to 9 times slower than the asm versions on x86 for both, but we had the strange mixture of all 6 variants of remainder in asm and only 1 of 6 variants of fmod in asm. MFC r305384 (by bde): Disconnect the "optimized" asm variants of cos(), sin() and tan() from the build on i386. Leave them in the source tree for regression tests. The asm functions were always much less accurate (by a factor of more than 10**18 in the worst case). They were faster on old CPUs. But with each new generation of CPUs they get relatively slower. The double precision C version's average advantage is about a factor of 2 on Haswell. The asm functions were already intentionally avoided in float and long double precision on i386 and in all precisions on amd64. Float precision and amd64 give larger advantages to the C version. The long double precision C code and compilers' understanding of long double precision are not so good, so the i387 is still slightly faster for long double precision, except for the unimportant subcase of huge args where the sub-optimal C code now somehow beats the i387 by about a factor of 2. MFC r305385 (by bde): Oops, the previous i386 version of e_fmodf.S and e_fmodl.S was actually the amd64 version.

This corresponds to 5.0.1 rc2. MFC r326831: Pull in r315334 from upstream lld trunk (by Rafael Espindola): Don't create a dummy __tls_get_addr. We just don't need one with the current setup. We only error on undefined references that are used by some relocation. If we managed to relax all uses of __tls_get_addr, no relocation uses it and we don't produce an error. This is less code and fixes the case were we fail to relax. Before we would produce a broken output, but now we produce an error. Pull in r320390 from upstream lld trunk (by Rafael Espindola): Create reserved symbols early so they can be versioned. This fixes pr35570. We were creating these symbols after parsing version scripts, so they could not be versioned. We cannot move the version script parsing later because we need it for lto. One option is to move both addReservedSymbols and createSyntheticSections earlier. The disadvantage is that some sections created by createSyntheticSections replace other input sections. For example, gdb index replaces .debug_gnu_pubnames, so it wants to run after gc sections so that it can set S->Live to false. What this patch does instead is to move just the ElfHeader creation early. Pull in r320412 from upstream lld trunk (by Rafael Espindola): Handle symbols pointing to output sections. Now that gc sections runs after linker defined symbols are added it can see symbols that point to an OutputSection. Should fix a bot failure. Pull in r320431 from upstream lld trunk (by Peter Collingbourne): ELF: Do not follow relocation edges to output sections during GC. This fixes an assertion error introduced by r320390. Differential Revision: https://reviews.llvm.org/D41095 Together these fix handling of reserved symbols, in particular _end, which is needed to make brk(2) and sbrk(2) work correctly.

The mergeinfo confuses Subversion enormously, and these directories will just use the mergeinfo for llvm itself. MFC r312765: Pull in r276136 from upstream llvm trunk (by Wei Mi): Use ValueOffsetPair to enhance value reuse during SCEV expansion. In D12090, the ExprValueMap was added to reuse existing value during SCEV expansion. However, const folding and sext/zext distribution can make the reuse still difficult. A simplified case is: suppose we know S1 expands to V1 in ExprValueMap, and S1 = S2 + C_a S3 = S2 + C_b where C_a and C_b are different SCEVConstants. Then we'd like to expand S3 as V1 - C_a + C_b instead of expanding S2 literally. It is helpful when S2 is a complex SCEV expr and S2 has no entry in ExprValueMap, which is usually caused by the fact that S3 is generated from S1 after const folding. In order to do that, we represent ExprValueMap as a mapping from SCEV to ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a} into the ExprValueMap when we create SCEV for V1. When S3 is expanded, it will first expand S2 to V1 - C_a because of S2->{V1, C_a} in the map, then expand S3 to V1 - C_a + C_b.

Having some warning controls in the Makefile and some in the source code is surprising. Pragmas have the advantage that they leave the warnings enabled for more code, but that advantage isn't very relevant in these cases. libthr: fix warnings from GCC when WARNS=6 Fix warnings about: - redundant declarations - a local variable shadowing a global function (dlinfo) - an old-style function definition (with an empty parameter list) - a variable that is possibly used uninitialized libthr: prevent setcontext() from masking SIGTHR __thr_setcontext() mistakenly tested for the presence of SIGCANCEL in its local ucontext_t instead of the parameter. Therefore, if a thread calls setcontext() with a context whose signal mask contains SIGTHR (a.k.a. SIGCANCEL), that signal will be blocked, preventing the thread from being cancelled or suspended.
