2020-06-18avoid -Wpointer-compare warning which broke build with clang 10jsg2-2/+2
2020-06-04Set max atomic size for PowerPC.gkoehler1-1/+4
32-bit PowerPC doesn't have instructions for lock-free atomic ops on 8-byte values, and needs libcalls like __atomic_fetch_add_8(). In code like "_Atomic long long a; a++;", clang doesn't emit a libcall. This was causing linker errors on symbols like __sync_fetch_and_add_8. Now that LLVM knows the max atomic size, its AtomicExpandPass changes these 8-byte ops into libcalls. ok mortimer@

All functional changes were committed already, this updates the version number, Module::Corelist, and documentation.

2020-05-30Switch Powerpc64 Big Endian to ELFv2 on OpenBSD, as least for now.drahn1-0/+2
This should simplify bringup and make it easier to support Big Endian and Little Endian with the same code. May be reconsidered if it causes too many problems with Ports. ok kettenis@

2020-05-30Initial set of changes to build powerpc64 toolchain.drahn2-5/+5
Disable PIC/PIE for powerpc64 for now.
2020-05-29Adjust some PPC ELF code to return -1 instead of doing pointerpatrick1-1/+1
arithmetics on NULL, like we did in r1.21 on elflink.c, to stop clang from complaining when setting up a cross-toolchain. ok kettenis@
2020-05-25PowerPC: optimize away the frame pointer.gkoehler1-3/+4
clang defaulted to -fomit-frame-pointer when optimizing PowerPC code for Linux and NetBSD. Now do it for all systems, including OpenBSD. This affects both 32-bit and powerpc64 code. ok kettenis@
2020-05-23Use a distinct trap code with retguard on mips64.visa1-2/+3
This lets the kernel detect retguard traps and send SIGABRT instead of SIGEMT. SIGEMT does not indicate correctly the nature of the error (stack overflow, violation of control flow). It can confuse the user to restart the program without further investigation. Prompted by and OK deraadt@ OK mortimer@

2020-05-02Don't make an illegal adde. Avoids fatal error on PowerPC.gkoehler1-1/+3
When the DAG truncates an ISD::ADDE node, DAGCombiner may optimize it by making an adde with smaller operands. PowerPC has i1 registers, and may truncate an i32 adde to i1, but an i1 adde is not legal for PowerPC, and the legalize-ops phase can't fix it. This was causing "fatal error: error in backend: Cannot select..." cwen@ reported the error ok mortimer@ kettenis@ deraadt@
2020-04-25Note extra Term-ReadKey build dependency on Cwdafresh11-0/+1

https://metacpan.org/pod/release/SHAY/perl-5.30.2/pod/perldelta.pod Incompatible Changes There are no changes intentionally incompatible with 5.30.0. Updated Modules and Pragmata * Compress::Raw::Bzip2 has been upgraded from version 2.084 to 2.089. * Module::CoreList has been upgraded from version 5.20191110 to 5.20200314. Selected Bug Fixes * printf() or sprintf() with the %n format no longer cause a panic on debugging builds, or report an incorrectly cached length value when producing SVfUTF8 flagged strings. * A memory leak in regular expression patterns has been fixed. * A read beyond buffer in grok_infnan has been fixed. * An assertion failure in the regular expression engine has been fixed. * (?{...}) eval groups in regular expressions no longer unintentionally trigger "EVAL without pos change exceeded limit in regex".

2020-01-03avoid build race condition: our make has an "expensive job" heuristicespie1-3/+7
which means we do stop creating other jobs as soon as we run something looking like "make" to avoid unwanted recursion, so you would never hit that. But in binutils-2.17, the developers changed all/info to do recursive makes with some of the same dependencies. Calling both at the same time becomes an obvious race, and should be fixed for no other reason than correctness. okay guenther@

2019-11-09Move the hashed __retguard_* symbols into individual sections and markguenther1-3/+5
them as COMDATs so that the linker can individually discard them, instead of just ignoring duplicate symbols but keep the (duplicate) space. On amd64, this reduces the size of the kernel OPENBSD_RANDOM segment by 82% and the libc OPENBSD_RANDOM segment by 15%. A port that tb@ is working on experienced a 97.3% reduction...which let it actually run. ok mortimer@ deraadt@

2019-10-25Add retguard for octeon/mips64.mortimer10-4/+444
For this architecture we use separate retguard prologue and epilogue code for static or PIC code. In the PIC case we use some additional code before the retguard epilogue to recover the function start address and the GOT pointer in order to get the per-function random cookie.
