Description

The logic in fpinit_ASL() (src/asl/solvers/fpinit.c) seems to be x86-focused. Problem reported upstream. I tried to fix the build with a patch for arm, loosely following previous code there for other architectures, but maybe it have been being developed for too long on x86 only. https://github.com/ampl/mp/issues/25 On second thought, I think it may be another issue. The SFPC instruction should receive a single argument. From the manual I use for s390 reference. [RRE]
is the instruction format, not an argument.
SET FPC
SFPC R [RRE]
'B384' //////// R1 ////////
.---------------.-------.---.------.
0 16 24 31
The contents of bit positions 32-63 of of the
general register designated by R1 are placed in
the FPC (floating-point-control) register.
All of bits 32-63 corresponding to unassigned bit
positions in the FPC must be zero; otherwise, a
specification exception is recognized. Bits 0-31 of
the general register are ignored.
Condition Code: The code remains unchanged.
Bits other than 62 and 63 of the second-operand
address are ignored.
Condition Code: The code remains unchanged.
IEEE Exception Conditions: None.
Program Exceptions:
* Data with DXC 2, BFP instruction
* Operation (if the BFP facility is not installed)
Translating 0x27f (639) to the FPC bits, it looks like some translation should be done, it maps to: 0x2f == 0b1001111111 0 IEEE-invalid-operation mask 1 1 IEEE-division-by-zero mask 1 2 IEEE-overflow mask 1 3 IEEE-underflow mask 1 4 IEEE-inexact mask 1 5 (reserved) 1 6 (reserved) 1 7 (reserved) 0 8 IEEE-invalid operation flag 0 9 IEEE-division by zero flag 0 ... so, the illegal instruction should be due to bits 5 and 6 set. ops, bit 9 above is 1... I tried $ s390-koji build --scratch rawhide /home/pcpa/fedora/mp/mp-1.3.0-3.fc22.src.rpm Did need to comment "BuildRequires: python-sphinx-latex", but it still failed, can you please give build it on an environment with a shell to see if you can have more details of the failure? http://s390.koji.fedoraproject.org/kojifiles/work/tasks/6258/1716258/build.log ... 21/29 Test #21: aslexpr-test .....................
