fetch: MFC: make -S argument accept values > 2GB
Use strtoll() to parse the argument of the -S option.
FreeBSD has supported 64 bit file offsets for more than 25 years on
all architectures and off_t is a 64 bit integer type for that reason.
While strtol() returns a 64 bit value on 64 LP64 architectures, it
is limit to 32 bit on e.g. i386. The strtoll() function returns a 64
but result on all supported architectures and therefore supports the
possible file lengths and file offsets on 32 bit archtectures.

Update Subversion to 1.14.1 LTS. See contrib/subversion/CHANGES for a
summary of changes, or for a more thorough overview:
https://subversion.apache.org/docs/release-notes/1.14
NOTE 1: There is no need to dump and reload repositories, and the
working copy format is still the same as Subversion 1.8 through 1.13.
NOTE 2: The upstream release also contains a fix for a security issue in
mod_dav_svn (CVE-2020-17525), but since we do not build or use any
Apache modules, it is not an issue for the FreeBSD base system.

MFC: Fix calendar -a processing of files included in the user's home directory
The existing code performed a chdir() into the home directory, but the
parser fell back to using the invoking user's home directory as the base
directory for the search for an include file.
Since use of the -a option is limited to UID==0, the directory searched
was typically ~root/.calendar, not the .calendar directory of the user
whose file is being processed.

MFC r348347 (by jhibbits):
Add missing powerpc64 relocation support to libdwarf
Summary:
Due to missing relocation support in libdwarf for powerpc64, handling of dwarf
info on unlinked objects was bogus.
Examining raw dwarf data on objects compiled on ppc64 with a modern compiler
(in-tree gcc tends to hide the issue, since it only rarely generates relocations
in .debug_info and uses DW_FORM_str instead of DW_FORM_strp for everything), you
will find that the dwarf data appears corrupt, with repeated references to the
compiler version where things like types and function names should appear.
This happens because the 0 offset of .debug_str contains the compiler version,
and without applying the relocations, *all* indirect strings in .dwarf_info will
end up pointing to it.
This corruption then propogates to the CTF data, as ctfconvert relies on
libdwarf to read the dwarf info, for every compiled object (when building a
kernel.)
However, if you examine the dwarf data on a compiled executable, it will appear
correct, because during final link the relocations get applied and baked in by
the linker.

addr2line: Cache CU DIEs upon a successful address lookup.
Previously, addr2line would sequentially search all CUs for each input
address. For some uses, notably syzkaller's code coverage map generator,
this was extremely slow. Add a CU cache into which entries are added
following a successful lookup, and search the cache before falling back
to a scan. When translating a large number of addresses this yields
slightly better performance than GNU addr2line.
Garbage-collect an unused hash table which appears to have been intended
for the same purpose. A hash table doesn't seem particularly suitable
since each CU spans a range of addresses.

MFC r363064,363067,363081,363136: optimize install(1) a bit.
Currently, "install -s -S" behaviour is inefficient for upgrade. First it finds that destination file already exists and copies source file to temporary file. Then it calls strip(1) with name of temporary file as single agrument and our strip(1) creates another temporary file in the /tmp (or TMPDIR) making another copy that is finally copied to DESTDIR third time. Meantime, strip(1) has an option "-o dst" to specify destination so install(1) is allowed to skip initial copying from obj to DESTDIR. This change makes it do so. This optimization descreases total amount of data sent to both of /tmp and DESTDIR during "make installworld" by 32% or so. See the differential for details.

MFC r360702: Merge commit 4ca2cad94 from llvm git (by Justin Hibbits): [PowerPC] Add clang -msvr4-struct-return for 32-bit ELF Summary: Change the default ABI to be compatible with GCC. For 32-bit ELF targets other than Linux, Clang now returns small structs in registers r3/r4. This affects FreeBSD, NetBSD, OpenBSD. There is no change for 32-bit Linux, where Clang continues to return all structs in memory. Add clang options -maix-struct-return (to return structs in memory) and -msvr4-struct-return (to return structs in registers) to be compatible with gcc. These options are only for PPC32; reject them on PPC64 and other targets. The options are like -fpcc-struct-return and -freg-struct-return for X86_32, and use similar code. To actually return a struct in registers, coerce it to an integer of the same size. LLVM may optimize the code to remove unnecessary accesses to memory, and will return i32 in r3 or i64 in r3:r4.

ValueTracking's matchSelectPattern() may rely on overflow (nsw, etc) or other flags when detecting patterns such as min/max/abs composed of compare+select. But the value numbering / hashing mechanism used by EarlyCSE intersects those flags to allow more CSE. Several alternatives to solve this are discussed in the bug report. This patch avoids the issue by doing simple matching of min/max/abs patterns that never requires instruction flags. We give up some CSE power because of that, but that is not expected to result in much actual performance difference because InstCombine will canonicalize these patterns when possible. It even has this comment for abs/nabs: /// Canonicalize all these variants to 1 pattern. /// This makes CSE more likely. (And this patch adds PhaseOrdering tests to verify that the expected transforms are still happening in the standard optimization pipelines. I left this code to use ValueTracking's "flavor" enum values, so we don't have to change the callers' code. If we decide to go back to using the ValueTracking call (by changing the hashing algorithm instead), it should be obvious how to replace this chunk.

This should fix "Assertion failed: (idx < size()), function operator[], file /usr/src/contrib/llvm/include/llvm/ADT/SmallVector.h, line 153" when building the graphics/mesa-dri port for the PowerPC64 ELFv2 ABI.

Reported by: mmel MFC r355803 (by mmel): Fix LLVM libunwnwind _Unwind_Backtrace symbol version for ARM. In original GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 version for all architectures but ARM. For ARM should be publishes with GCC_4.3.0 version. This was originally omitted in r255095, fixed in r318024 and omitted aging in LLVM libunwind implementation in r354347. For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0 version , (because this is right original version) and again as normal(not-default) with GCC_3.3 version (to maintain ABI compatibility compiled/linked with wrong pre r318024 libgcc) PR: 233664 |

MFC r357875: diff: fix segfault with --tabsize and no/malformed argument
--tabsize was previously listed as optional_argument, but didn't account for the optionality of it in the argument handling. This is irrelevant -- the manpage doesn't indicate that the argument is optional, and indeed there's no clear interpretation of omitting the argument because there's no other side effect of --tabsize. The "malformed" argument part of the header on this message is simply referring to usage like this: % diff --tabsize 4 A B With an optional_argument, the argument must be attached to the parameter directly (e.g. --tabsize=4), so the argument is effectively NULL with the above invocation as if no argument had been passed.

MFC r356723-r356725: diff(1) return value checks
r356723: mkstemp returns -1 r356724: asprintf returns -1, not an arbitrary value < 0. Also upon error the (very sloppy specification) leaves an undefined value in *ret, so it is wrong to inspect it, the error condition is enough. r356725: When system calls indicate an error they return -1, not some arbitrary value < 0. errno is only updated in this case. |

MFC r359680: mail/gprof/tip: tap with the ugly stick
The ugly stick here is this bit in the respective headers: #ifndef EXTERN #define EXTERN extern #endif with a follow-up #define EXTERN in a single .c file to push all of their definitions into one spot. A pass should be made over these three later to push these definitions into the correct files instead, but this will suffice for now and at a more leisurely pace. |
