Hi Jeff,

What has changed on your end in R3.14 branch?

By the way it also breaks for vxWorks 6.6 as well.

So, maybe you can reproduce on your end.

../../../../src/cas/generic/st/casStreamOS.cc:283: error: this is the insn:

       (mem/s/c:DF (plus:SI (reg/f:SI 113 sfp)

   (nil))

make[2]: *** [build.install] Error 2

make[1]: *** [cas.install] Error 2

Ernest,

One has to wonder if WRS runs the regression tests on
their vxWorks variants of the GNU compilers.

If this keeps causing problems then perhaps we should push the toothpaste in the tube at that spot in the source code where the compiler has troubles.

I checked with Eric and we don’t have vxWorks 6.8 installed here
but Eric mentioned that he was fairly certain that they might
have it installed at the APS, and if so perhaps I could
log in up there and have a look at the issue.

I wonder if the APS has seen this issue since they maybe have vxWorks 6.8 there? Does the problem occur when the vxWorks

6.8 gnu compiler isn't patched?

Jeff

Hi,

I applied the following patch from WindRiver:


NAME:GNU 4.1.2 Cumulative Patch for VxWorks 6.7 AND 6.8
(PowerPC)SUMMARY:Latest GNU 4.1.2 Cumulative Patch for VxWorks 6.7 and
6.8 (PowerPC)PRODUCT VERSION:GNU Tools 4.1.2TYPE:PatchDOWNLOADS:1.
cum.vxw6-4.1.2-ppc.2010aug12.zip

<https://support.windriver.com/olsPortal/download?docId=35427&contentId=0210
02

_0001>DESCRIPTION:


I also recall an earlier patch.
So, something is different as I am not getting this problem on EPICS
R3.14.11

Thanks,
Ernest

Hi,

Latest snapshot of EPICS R3.14.12 does not compile under vxWorks 6.8
on the following target: vxWorks-ppc604

I think Jeff and I have already seen this compiler bug in vxWorks 6.6.
I will confirm that WRS has a compiler patch upstream
