Bug ID: 71145
Summary: Alpha: Error: No lda !gpdisp!278 was found
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mcree at orcon dot net.nz
Target Milestone: ---
Target: alpha
In certain packages on debian-ports build logs for the Alpha architecture I am
seeing compile failures of the nature:
{standard input}: Assembler messages:
{standard input}:7233: Error: No lda !gpdisp!278 was found
One such example is src/player/SubscriberInfo.o of the source package libavg
(build log is at
https://buildd.debian.org/status/fetch.php?pkg=libavg&arch=alpha&ver=1.8.1-2.1&stamp=1461798687).
Compile failure happens with gcc-5 (Debian version 5.3.1-19) and also with
gcc/g++ (7.0.0) built from the trunk about a week ago (though the line number
of the failure changes).
I will attempt to attach preprocessed source of SubscriberInfo.cpp from libavg.
Um, no I can't; it's too large for the 1000kB limit. How can I provide the
file?
Compiling with:
g++ -pthread -ffast-math -pipe -g -O2 -c SubscriberInfo-preprocessed.cpp -fPIC
-o .libs/SubscriberInfo.o
results in the No lda gpdisp error.
It successfully compiles if the -O2 is changed to -O0 or -O1.
