* META_MODE: No need to fix the link in this case.Bryan Drewery2015-09-181-1/+1
| | | | | | | | | | | | | | The exists(${DESTDIR}...) check runs with DESTDIR being blank. When the target runs it does have DESTDIR=${STAGE_OBJTOP} via bsd.sys.mk. This results in the first execution warning that the symlink is missing. The second run does run fine. However, this chflags is not needed at all for META_MODE/STAGING since we never had this path being a schg file while using META_MODE.

* Fix how we place each objects thread local data. The code used was basedAndrew Turner2015-09-012-4/+4
| | | | | | | | | | | | | | | | | | | | | | on the Variant II code, however arm64 uses Variant I. The former placed the thread pointer after the data, pointing at the thread control block, while the latter places these before said data. Because of this we need to use the size of the previous entry to calculate where to place the current entry. We also need to reserve 16 bytes at the start for the thread control block. This also fixes the value of TLS_TCB_SIZE to be correct. This is the size of two unsigned longs, i.e. 2 * 8 bytes. While here remove the bogus adjustment of the pointer in the R_AARCH64_TLS_TPREL64 case. It should be the offset of the data relative to the thread pointer, including the thread control block.

| | | | | | | | | | | | | | | | | | | | | have TLS program header. This is needed on architectures with Variant I tls, that is arm, arm64, mips, and powerpc. These place the thread control block at the start of the buffer and, without this, this data may be trashed. This appears to not be an issue on mips or powerpc as they include a second adjustment to move the thread local data, however this is on arm64 (with a future change to fix placing this data), and should be on arm. I am unable to trigger this on arm, even after changing the code to move the data around to make it more likely to be hit. This is most likely because my tests didn't use the variable in offset 0.

* Disable SSE in libthrEric van Gyzen2015-08-052-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang emits SSE instructions on amd64 in the common path of pthread_mutex_unlock. If the thread does not otherwise use SSE, this usage incurs a context-switch of the FPU/SSE state, which reduces the performance of multiple real-world applications by a non-trivial amount (3-5% in one application). Instead of this change, I experimented with eagerly switching the FPU state at context-switch time. This did not help. Most of the cost seems to be in the read/write of memory--as kib@ stated--and not in the #NM handling. I tested on machines with and without XSAVEOPT. One counter-argument to this change is that most applications already use SIMD, and the number of applications and amount of SIMD usage are only increasing. This is absolutely true. I agree that--in general and in principle--this change is in the wrong direction. However, there are applications that do not use enough SSE to offset the extra context-switch cost. SSE does not provide a clear benefit in the current libthr code with the current compiler, but it does provide a clear loss in some cases. Therefore, disabling SSE in libthr is a non-loss for most, and a gain for some. I refrained from disabling SSE in libc--as was suggested--because I can't make the above argument for libc. It provides a wide variety of code; each case should be analyzed separately. https://lists.freebsd.org/pipermail/freebsd-current/2015-March/055193.html Suggestions from: dim, jmg, rpaulo Approved by: kib (mentor) MFC after: 2 weeks Sponsored by: Dell Inc.

Unfortunately, as we make use of libc, we are unable to disallow rtld from using floating-point register without also doing the same for the parts of libc we use, or by limiting what _rtld_bind is able to call.

* Add a workaround to correctly align the stack before calling into C code.Andrew Turner2015-06-221-3/+7
| | | | | | | | | | | | | | | | | When enough time has passed for users to update their userland the kernel fix will be applied. This will change the ABI to have x0 point to the args and sp be correctly aligned. It is expected this compatibility code can be removed when the kernel and qemu usermode emulation have both been updated for the new ABI. This fixes clang failures, and most likely other crashes.
