Happily building and using guile on osx 10.12, 10.13, and Ubuntu 16.04. osx 10.11, though, crashes when I just evaluate (display (version)), or sometimes while building. Happens whether I build it myself, or use brew. Happens on more than one machine, too. This is with xcode 7.1: $ cc --version Apple LLVM version 7.0.0 (clang-700.1.76) Target: x86_64-apple-darwin15.6.0 Thread model: posix I think it also happens with xcode 7.3.1: $ cc --version Apple LLVM version 7.3.0 (clang-703.0.31) Target: x86_64-apple-darwin15.6.0 Thread model: posix InstalledDir: /Applications/Xcode7.3.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin Haven't tried the latest, xcode 8.2.1. For instance: $ brew install guile $ guile ... scheme@(guile-user)> (display (version)) Illegal instruction: 4 Here's another: building from source fails early with Making all in bootstrap GUILE_AUTO_COMPILE=0 \ ../meta/build-env \ guild compile --target="x86_64-apple-darwin15.6.0" \ -O1 \ -L "/Users/buildbot/src/yobuild/recipes/guile/btmp/guile-2.2.3/module" \ -L "/Users/buildbot/src/yobuild/recipes/guile/btmp/guile-2.2.3/guile-readline" \ -o "ice-9/eval.go" "../module/ice-9/eval.scm" make[2]: *** [ice-9/eval.go] Illegal instruction: 4 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 Anyone run into this before? - Dan ^ permalink raw reply [flat|nested] 4+ messages in thread

Also had to do sudo /usr/sbin/DevToolsSecurity --enable Here's a backtrace: * thread #1: tid = 0x1628f8, 0x00000001003e95be libgmp.10.dylib`__gmpn_mul_1 + 94, queue = 'com.apple.main-thread', stop reason = EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0) frame #0: 0x00000001003e95be libgmp.10.dylib`__gmpn_mul_1 + 94 libgmp.10.dylib`__gmpn_mul_1: -> 0x1003e95be <+94>: mulxq (%rsi), %rbx, %rax Guess what? This machine is a i7-3720QM (in a Macbook Pro 9,1), which doesn't support MULX. (It's 2012 Ivy Bridge, which is just pre-Haswell.) $ gobjdump -d libgmp.dylib | grep mulx confirms the presence of the mulx instruction. So my gmp was built wrong for this machine. (There was a related bugfix for low-end cpus in gmp 6.1.1, but I've got 6.1.2, and no low-end cpus.) Bit of a mystery, then, but nothing to do with guile. - Dan ^ permalink raw reply [flat|nested] 4+ messages in thread

If you build and run everything on the same machine, none of this is likely to affect you; this is only for the case where each library is built by a random machine from a buildbot pool. I had been paying attention to the AVX1.0 divide across our buildbot fleet, and arranged to segregate MacPro5,1 machines off in their own pool, to avoid crashes from vxorps (an AVX instruction) in ImageMagick; here's the output of sysctl -n hw.model machdep.cpu.brand_string machdep.cpu.features on our machines, with boring bits removed: MacPro5,1 E5620 SMX SSE4.2 MacBookPro8,2 i7-2720QM SMX SSE4.2 x2APIC XSAVE OSXSAVE TSCTMR AVX1.0 Macmini6,2 i7-3615QM SSE4.2 x2APIC XSAVE OSXSAVE TSCTMR AVX1.0 RDRAND F16C MacBookPro9,1 i7-3720QM SMX SSE4.2 x2APIC XSAVE OSXSAVE TSCTMR AVX1.0 RDRAND F16C MacBookPro11,2 i7-4870HQ SMX FMA SSE4.2 x2APIC MOVBE XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C MacBookPro11,2 i7-4960HQ SMX FMA SSE4.2 x2APIC MOVBE XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C MacBookPro11,5 i7-4980HQ SMX FMA SSE4.2 x2APIC MOVBE XSAVE OSXSAVE SEGLIM64 TSCTMR AVX1.0 RDRAND F16C MULX is a nice Intel instruction that was introduced in 2013 in non-low-end Haswell chips. https://software.intel.com/sites/default/files/m/f/7/c/36945 says one detects it like this: CPUID.(EAX=07H, ECX=0H):EBX.BMI2[bit 8]: if 1 indicates the processor supports the second group of advanced bit manipulation extensions (BZHI, MULX, PDEP, PEXT, RORX, SARX, SHLX, SHRX); http://publicclu2.blogspot.com/2013/05/flags-in-x86-linuxs-proccpuinfo.html clarifies that, on Linux, /proc/cpuinfo will contain the string BMI2 if MULX is present. This evidently is also true of sysctl -n machdep.cpu.leaf7_features on mac, which says: MacPro5,1 E5620 MacBookPro8,2 i7-2720QM Macmini6,2 i7-3615QM SMEP ERMS RDWRFSGS MacBookPro9,1 i7-3720QM SMEP ERMS RDWRFSGS MacBookPro11,2 i7-4870HQ SMEP ERMS RDWRFSGS TSC_THREAD_OFFSET BMI1 HLE AVX2 BMI2 INVPCID RTM MacBookPro11,2 i7-4960HQ SMEP ERMS RDWRFSGS TSC_THREAD_OFFSET BMI1 HLE AVX2 BMI2 INVPCID RTM FPU_CSDS MacBookPro11,5 i7-4980HQ SMEP ERMS RDWRFSGS TSC_THREAD_OFFSET BMI1 AVX2 BMI2 INVPCID FPU_CSDS which means I have three basic groups: 1) no AVX: (MacPro5,1; circa 2010) 2) AVX but no BMI2 (circa 2011-2012) 3) AVX and BMI2 (MacBookPro11.2, 11.5; circa 2013-2015) I'm sure other people will have different needs, but for me, segregating shared build machines into those three pools -- and/or sticking with two pools and disabling use of MULX in gmp -- should avoid the crashes I saw due to ImageMagick and GMP cpu specific instruction assumptions. It'd be nice if gmp and imagemagick were more agile about cpu feature detection, and did (more of) it at runtime, but that's life. - Dan On Sun, Dec 31, 2017 at 5:53 PM, Dan Kegel <dank@kegel.com> wrote: > On Sat, Dec 30, 2017 at 3:31 PM, Matt Wette <matt.wette@gmail.com> wrote: >>> On Dec 30, 2017, at 2:32 PM, Dan Kegel <dank@kegel.com> wrote: >>> osx 10.11, though, crashes when I just evaluate (display (version)), >>> or sometimes while building. >> >> I have not seen that on macOS before, but previously ran into other issues.
