This is partially a 2.078.0 regression, but I wasn't sure about filing a new issue since it seems to be a duplicate of this bug. ----------------------------- void main() { } struct Line { double slope; double intercept; } Line nLineProjection(double[] historicData) { Line projLine; projLine.intercept = historicData[$-1] + projLine.slope; return projLine; } ----------------------------- $ dmd -O test.d tym = x1d Internal error: dmd/backend/cgxmm.c 684 $ dmd --version DMD64 D Compiler v2.078.0 Copyright (c) 1999-2017 by The D Language Foundation written by Walter Bright -- |

https://issues.dlang.org/show_bug.cgi?id=15206 --- Comment #4 from briancschott@gmail.com --- It seems that the problem is in the allocreg function called from loaddata. I added some debugging printfs before and after calls to `allocreg` and I see the following: before: tym = 0x1d, forregs = 0x020000, reg = BP|SI|DI|R10|R12|R15|XMM0|XMM1|XMM3|XMM4|XMM5|XMM6|XMM7|PSW|NOREG|RMload after: tym = 0x1d, forregs = 0x020000, reg = AX|SP It seems that the `forregs` variable (The `pretregs` parameter to allocreg) is not getting modified properly. It still has the value 0x20000, which matches the XMMREGS mask even though `allocreg` has correctly removed all the XMM registers from the list of valid registers in the `reg` variable. Because this `forregs` variable is not masked out by XMMREGS, there is a call to `xmmload` even though `xmmload` doesn't support `tym` values of 0x1d. -- |
