I am importing llvm, clang, compiler-rt, libc++, libunwind, lld, lldb, and openmp 9.0.0 into the projects/clang900-import branch. As of 2019-09-17, this branch contains the equivalent of upstream's 9.0.0 rc4, and it has been synchronized with base r352435. Please perform an exp-run against this branch. [for convenience, bug 236062 was the previous clang 8.0.0 exp-run]

(In reply to Antoine Brodin from comment #1) > lang/gcc* fail to build, for instance: Hm, that is very strange, I've just built those ports successfully, and there were no linking errors whatsoever?

I doubt 2 hosts are busted for the same ports.

Submitted bug 240701 for textproc/groff.
Ok, at least I have been able to reproduce the gcc failures on a cleanly installed VM. It looks like in such an environment, the gencondmd.c tool is compiled without any optimization, causing the references to e.g. ix86_isa_flags and similar variables, which are declared in gcc's options.h, but do not seem to be actually *defined* anywhere. For some reason, on my own machine, gencondmd.c is compiled with -O2 -pipe, and that causes all the references to disappear, hence there are no linking errors. As to *why* that is, I'm still in the dark. Gcc's build system is notoriously muddy, so it is hard to see where the options are coming from, and what is supposed to happen. In short: 1) For the initial generator tools such as 'gencondmd' the flag -DGENERATOR_FILE is used, causing option flags such as ix86_isa_flags to be declared as global extern variables. 2) However, there is no clear location where these global variables are *defined*, as options.c only has them as members of a gcc_option struct. 3) By accident, the references to these non-existing symbols can get optimized out, since they are all in unused inline functions.
A commit references this bug: Author: dim Date: Sat Sep 21 21:01:39 UTC 2019 New revision: 352586 URL: https://svnweb.freebsd.org/changeset/base/352586 Log: Pull in r371557 from upstream clang trunk (by Richard Smith): When evaluating a __builtin_constant_p conditional, always enter constant-folding mode regardless of the original evaluation mode. In order for this to be correct, we need to track whether we're checking for a potential constant expression or checking for undefined behavior separately from the evaluation mode enum, since we don't want to clobber those states when entering constant-folding mode. This should fix "ld: error: undefined symbol: ix86_isa_flags" (and many other symbol names) during the initial stages of the lang/gcc* ports. The issue was that without optimization, the __builtin_constant_p() expressions generated in gencondmd.c would emit references to global variables that were undefined, such as ix86_isa_flags.

Is this going to be merged into /stable/11? Like bug 215193 predicted old compiler and, especially, old libc++ will put a strain on 11.4 support in ports/. See emulators/rpcs3/files/patch-libc++8 for an early canary.
(In reply to Jan Beich from comment #13) I have nothing against it, but we're in code slush now? Merging 9.0.1 could be done, but you could consider it to be quite a big change...
(In reply to Dimitry Andric from comment #14) I think it should be fine, especially considering you have merged this to stable/12.

Too many warnings are being disabled too quickly. Warnings are important to keeping libc++ correct. This patch re-enables two warnings: -Wconstant-evaluated and -Wdeprecated-copy. In future, all warnings disabled for the test suite should require an attached bug. The bug should state the plan for re-enabling that warning, or a strong case why it should remain disabled. This should fix a number of new g++ 9 warnings. Requested by: rlibby MFC r356100: Merge commit d3aeac8e2 from llvm git (by Justin Hibbits) [PowerPC] Only use PLT annotations if using PIC relocation model Summary: The default static (non-PIC, non-PIE) model for 32-bit powerpc does not use @PLT annotations and relocations in GCC. LLVM shouldn't use @PLT annotations either, because it breaks secure-PLT linking with (some versions of?) GNU LD. Update the available-externally.ll test to reflect that default mode should be the same as the static relocation, by using the same check prefix.

At compiling time, if clang can't decide if atomic operation can be lock free, it emits calls to external functions like `__atomic_is_lock_free`, `__c11_atomic_is_lock_free` and `__atomic_always_lock_free`, postponing decision to a runtime check. According to LLVM code documentation, the mechanism exists due to differences between x86_64 processors that can't be decided at runtime. On PowerPC and PowerPCSPE (32 bits), we already know in advance it can't be lock free, so we force the decision at compile time and avoid having to implement it in an external library. This patch was made after 32 bit users testing the PowePC32 bit ISO reported llvm could not be compiled with in-base llvm due to `__atomic_load8` not implemented.

This usually works but there are cases where the section may still be the same but the fragment may be another one. In that case we end forcing a %pcrel_lo relocation without any %pcrel_hi. This patch makes RISCVAsmBackend::shouldForceRelocation use the section, if any, to determine if the relocation must be forced or not.

Requested by: jhb MFC r356330: Merge commit da7b129b1 from llvm git (by James Clarke): [RISCV] Don't force Local Exec TLS for non-PIC Summary: Forcing Local Exec TLS requires the use of copy relocations. Copy relocations need special handling in the runtime linker when being used against TLS symbols, which is present in glibc, but not in FreeBSD nor musl, and so cannot be relied upon. Moreover, copy relocations are a hack that embed the size of an object in the ABI when it otherwise wouldn't be, and break protected symbols (which are expected to be DSO local), whilst also wasting space, thus they should be avoided whenever possible. As discussed in D70398, RISC-V should move away from forcing Local Exec, and instead use Initial Exec like other targets, with possible linker relaxation to follow. The RISC-V GCC maintainers also intend to adopt this more-conventional behaviour (see https://github.com/riscv/riscv-elf-psabi-doc/issues/122).

Requested by: jhb MFC r356701: Merge commit f46ba4f07 from llvm git (by Simon Atanasyan): [mips] Use less registers to load address of TargetExternalSymbol There is no pattern matched `add hi, (MipsLo texternalsym)`. As a result, loading an address of 32-bit symbol requires two registers and one more additional instruction: ``` addiu $1, $zero, %lo(foo) lui $2, %hi(foo) addu $25, $2, $1 ``` This patch adds the missed pattern and enables generation more effective set of instructions: ``` lui $1, %hi(foo) addiu $25, $1, %lo(foo) ``` Differential Revision: https://reviews.llvm.org/D66771 llvm-svn: 370196 Merge commit 59bb3609f from llvm git (by Simon Atanasyan): [mips] Fix 64-bit address loading in case of applying 32-bit mask to the result If result of 64-bit address loading combines with 32-bit mask, LLVM tries to optimize the code and remove "redundant" loading of upper 32-bits of the address. It leads to incorrect code on MIPS64 targets. MIPS backend creates the following chain of commands to load 64-bit address in the `MipsTargetLowering::getAddrNonPICSym64` method: ``` (add (shl (add (shl (add %highest(sym), %higher(sym)), 16), %hi(sym)), 16), %lo(%sym)) ``` If the mask presents, LLVM decides to optimize the chain of commands. It really does not make sense to load upper 32-bits because the 0x0fffffff mask anyway clears them. After removing redundant commands we get this chain: ``` (add (shl (%hi(sym), 16), %lo(%sym)) ``` There is no patterns matched `(MipsHi (i64 symbol))`. Due a bug in `SYM_32` predicate definition, backend incorrectly selects a pattern for a 32-bit symbols and uses the `lui` instruction for loading `%hi(sym)`. As a result we get incorrect set of instructions with unnecessary 16-bit left shifting: ``` lui at,0x0 R_MIPS_HI16 foo dsll at,at,0x10 daddiu at,at,0 R_MIPS_LO16 foo ``` This patch resolves two problems: - Fix `SYM_32/SYM_64` predicates to prevent selection of patterns dedicated to 32-bit symbols in case of using N64 ABI. - Add missed patterns for 64-bit symbols for `%hi/%lo`. Fix PR42736.

Requested by: arichards MFC r356789 (by arichardson): Merge commit 894f742acb from llvm git (by me): [MIPS][ELF] Use PC-relative relocations in .eh_frame when possible When compiling position-independent executables, we now use DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a 64-bit PC-relative ELF relocation so we cannot use sdata8 for the large code model case. When using the large code model, we fall back to the previous behaviour of generating absolute relocations. With this change clang-generated .o files can be linked by LLD without having to pass -Wl,-z,notext (which creates text relocations). This is simpler than the approach used by ld.bfd, which rewrites the .eh_frame section to convert absolute relocations into relative references. I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations for MIPS ouput at some point. However, I also checked that recent ld.bfd can process the clang-generated .o files so this no longer seems true.

Using the relocation against a data symbol (e.g. function pointer) will cause some linkers that don't ignore the hint in this case (e.g. LLD prior to commit 5bab291) to generate a relative branch to the data symbol which crashes at run time. Before this patch, LLVM was erroneously emitting these relocations against local-dynamic TLS function pointers and global function pointers with internal visibility.
