Hello Sitsofe, thanks for your help. ./configure --extra-cflags="-fno-asynchronous-unwind-tables" make -j worked. I am testing the new PCIe gen 4 NvMEs so I am glad it worked. One question, do you know when the "Poor windowsaio performance due to synchronization of writes unless --overwrite 1 is given (#833)" is going to be resolved? I also noticed that the queue depth indicated in FIO does not translate into PHY disk queue depth when first allocations are happening. I would need the symbols for FIO to troubleshoot further because our stack appears to be waiting Thanks Astolfo -----Original Message----- From: Sitsofe Wheeler <sitsofe@xxxxxxxxx> Sent: Sunday, October 27, 2019 1:34 PM To: Astolfo Rueda <astolfor@xxxxxxxxxxxxx> Cc: fio@xxxxxxxxxxxxxxx; Rebecca Cran <rebecca@xxxxxxxxxxxx> Subject: Re: build issue Hi, On Sat, 19 Oct 2019 at 08:11, Sitsofe Wheeler <sitsofe@xxxxxxxxx> wrote: > > Hi, > > On Fri, 18 Oct 2019 at 23:18, Astolfo Rueda <astolfor@xxxxxxxxxxxxx> wrote: > > > > Hello I am trying to build FIO and I get these errors. > > The server is windows 10, with latest Cygwin. > > > > What am I doing wrong? > > You're not doing anything wrong from what I can see - it looks like > sounds like some sort of compiler issue... > > > Thanks > > Astolfo > > > > > > /tmp/ccQfIUjv.s: Assembler messages: > > /tmp/ccQfIUjv.s:1188: Error: invalid register for .seh_savexmm > > make: *** [Makefile:376: filehash.o] Error 1 > > make: *** Waiting for unfinished jobs.... > > /tmp/ccZfFBQo.s: Assembler messages: > > /tmp/ccZfFBQo.s:3812: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3814: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3816: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3818: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3820: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3822: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3824: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3826: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3828: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3830: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3832: Error: invalid register for .seh_savexmm > > /tmp/ccZfFBQo.s:3834: Error: invalid register for .seh_savexmm > > make: *** [Makefile:379: options.o] Error 1 > > Hmm.

So I've managed to find a recent Xeon server with Windows VM and I see the compile errors you describe on it too. Doing make clean ./configure --extra-cflags="-fno-asynchronous-unwind-tables" make -j fixes the "invalid register for .seh_savexmm" error for me. Another workaround is to disable the generation of problematic AVX instructions: make clean ./configure --extra-cflags="-mno-avx512f" make -j but the binary made might be ever so slightly slower (and you'd need incredibly fast disks and when I did a quick check with the null ioengine I actually found the non-AVX512 version of fio was faster in my VM...). It looks like this is the "gcc/mingw-gcc fails to align the stack properly to Windows' requirements when using AVX 512 instructions" issue: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgcc.gnu.org%2Fbugzilla%2Fshow_bug.cgi%3Fid%3D65782&data=02%7C01%7Castolfor%40microsoft.com%7C4e168665a8dd437ebc9908d75b1d1392%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637078052750861103&sdata=mZDep3WBoQw7%2BJX7BS6Jixk105BQ2pNbuylAdlP%2B9hM%3D&reserved=0 https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgcc.gnu.org%2Fbugzilla%2Fshow_bug.cgi%3Fid%3D54412&data=02%7C01%7Castolfor%40microsoft.com%7C4e168665a8dd437ebc9908d75b1d1392%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637078052750861103&sdata=d1VKYkNJgDLB%2Fohlpp8KlcpKCcTtd6ergsbDL8yVflo%3D&reserved=0 https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F30928265%2Fmingw64-is-incapable-of-32-byte-stack-alignment-required-for-avx-on-windows-x64&data=02%7C01%7Castolfor%40microsoft.com%7C4e168665a8dd437ebc9908d75b1d1392%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637078052750861103&sdata=6z0fLsceHViOZ9Iac%2BJN%2B88hmvs7aDrYZCxwquem3cQ%3D&reserved=0 https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F43152633%2Finvalid-register-for-seh-savexmm-in-cygwin&data=02%7C01%7Castolfor%40microsoft.com%7C4e168665a8dd437ebc9908d75b1d1392%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637078052750871059&sdata=WkrV%2FyXZQ9f3eX5AEWk16%2FNJc2ufRFCuDvNLdGfaBSA%3D&reserved=0 -- Sitsofe | https://nam06.safelinks.protection.outlook.com/?url=http:%2F%2Fsucs.org%2F~sits%2F&data=02%7C01%7Castolfor%40microsoft.com%7C4e168665a8dd437ebc9908d75b1d1392%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637078052750871059&sdata=LtlvGTWKTyNKXOsHsNqp5s7JmEKmML2skKp2q%2B%2BPn50%3D&reserved=0
