d8a0c864 - Revert r344436, which was the merge of r344120.

Fri, 22 Feb 2019 10:06:34 +0000

Revert r344436, which was the merge of r344120.Currently stable/12 i386 installs old ld.bfd as ld (WITHOUT_LLD_IS_LD),which prevents ifunc relocations from working properly. If a staticbinary is linked, then it looses libc relocations needed.The stable i386 branch uses ld.lld for the world build (WITH_LLD_BOOTSTRAP),which is why static binaries from the base do not have the issue.Reported and diagnosted by: antoine List of files: /freebsd-12.1/lib/libc/Makefile

41b9df16 - Strip RCSID() and SCCSID() strings by default when building libc.

Tue, 03 Jul 2018 16:45:49 +0000

Strip __RCSID() and __SCCSID() strings by default when building libc.This is in preparation for changes to update the various ID strings inlibc's source. CSRG ID strings will use __SCCSID() and there are someexisting uses of __RCSID() for NetBSD ID strings already. These aregenerally under either an explicit #if 0 or an #ifdef LIBC_SCCS so areoff by default and this change preserves that existing behavior.Differential Revision: https://reviews.freebsd.org/D15830 List of files: /freebsd-12.1/lib/libc/Makefile

db08bfce - Created static libc PIC/no-SSP library to be used by rtld.

Wed, 09 May 2018 10:28:24 +0000

Created static libc PIC/no-SSP library to be used by rtld.Rtld is not compatible with SSP, and since we link libc_pic.a to rtldto have the basic support like memory and string copy functions, wehave to both carefully limit libc use, and to provide the ssp supportshims. This change makes the libc use in rtld more straighforward butstill limited, and allows to remove the shims, to be done in the nextcommit.Submitted by: Luis PiresReviewed by: bdrewery, brooksDifferential revision: https://reviews.freebsd.org/D15283 List of files: /freebsd-12.1/lib/libc/Makefile

d0fd0203 - Replace dot-dot relative pathing with SRCTOP-relative paths where possible

Fri, 20 Jan 2017 03:23:24 +0000

Replace dot-dot relative pathing with SRCTOP-relative paths where possibleThis reduces build output, need for recalculating paths, and makes it clearerwhich paths are relative to what areas in the source tree. The change inperformance over a locally mounted UFS filesystem was negligible in my testing,but this may more positively impact other filesystems like NFS.LIBC_SRCTOP was left alone so Juniper (and other users) can continue tomanipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) asinclude Makefiles with custom options.Discussed with: marcel, sjgMFC after: 1 weekReviewed by: emasteSponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D9207 List of files: /freebsd-12.1/lib/libc/Makefile

16808549 - Implement userspace gettimeofday(2) with HPET timecounter.

Wed, 17 Aug 2016 09:52:09 +0000

Implement userspace gettimeofday(2) with HPET timecounter.Right now, userspace (fast) gettimeofday(2) on x86 only works forRDTSC. For older machines, like Core2, where RDTSC is not C2/C3invariant, and which fall to HPET hardware, this means that the callhas both the penalty of the syscall and of the uncached hw behind theQPI or PCIe connection to the sought bridge. Nothing can me doneagainst the access latency, but the syscall overhead can be removed.System already provides mappable /dev/hpetX devices, which givesstraight access to the HPET registers page.Add yet another algorithm to the x86 'vdso' timehands. Libc is updatedto handle both RDTSC and HPET. For HPET, the index of the hpet deviceto mmap is passed from kernel to userspace, index might be changed andlibc invalidates its mapping as needed.Remove cpu_fill_vdso_timehands() KPI, instead require thattimecounters which can be used from userspace, to providetc_fill_vdso_timehands{,32}() methods. Merge i386 and amd64libc//sys/__vdso_gettc.c into one source file in the newlibc/x86/sys location. __vdso_gettc() internal interface is changedto move timecounter algorithm detection into the MD code.Measurements show that RDTSC even with the syscall overhead is fasterthan userspace HPET access. But still, userspace HPET is three-fourtimes faster than syscall HPET on several Core2 and SandyBridgemachines.Tested by: Howard Su Sponsored by: The FreeBSD FoundationMFC after: 1 monthDifferential revision: https://reviews.freebsd.org/D7473 List of files: /freebsd-12.1/lib/libc/Makefile
