Description: Under i686 architecture the creation of the luajittex format fails when run from the pacman hook. There is a illegal instruction message that can be reproduced my running fmtutil manually.

Which CPU are you running on ? I wonder if it is hardware dependent.
Comment by Stefan Husmann (stefanhusmann) - Wednesday, 27 July 2016, 07:17 GMT
A very old one, Pentium III 1 GHz in a HP Omnibook 6100.
Comment by Doug Newgard (Scimmia) - Wednesday, 27 July 2016, 14:01 GMT
illegal instruction is almost always hardware dependent. It means the program is trying to issue a hardware instruction that the CPU doesn't understand. This is most commonly SSE2.
Comment by Stefan Husmann (stefanhusmann) - Wednesday, 27 July 2016, 14:27 GMT
But shouldn't SSE2 instructions be forbidden in a binary claiming to support i686?
Comment by Doug Newgard (Scimmia) - Wednesday, 27 July 2016, 14:31 GMT
They should, but some build systems will include them when they detect the processor they're building on supports them.

Rebuilding texlive-bin with an unchanged PKGBUILD on the old laptop did not change the error.
Comment by Rémy Oudompheng (remyoudompheng) - Thursday, 28 July 2016, 06:31 GMT
Does the error happen in the binary itself or in runtime-generated code ? LuaJIT advertises that JIT is disabled when SSE2 is not supported.
Comment by Stefan Husmann (stefanhusmann) - Thursday, 28 July 2016, 17:35 GMT
It happens when running fmtutil-sys, also when the installfile does so during package installation.

Closing this as i686 is no longer supported.
