            Bug ID: 102339
           Summary: gm2 testsuite leaves many files behind
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: modula2
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: gaiusmod2 at gmail dot com
  Target Milestone: ---

After running the gm2 testsuite, there are almost 2000 files left behind in
gcc/testsuite/gm2.  All but a handful follow the same pattern, e.g.

wr.x0-wr_m2.o

I suspect this is a driver issue: m2-link-support.h has

#define SCAFFOLDNAME "%b_m2"

Since those files are purely temporary, I suspect (but haven't tried) that they
should be marked as such using %d.

There are only a few more:

* remaining objects:

cpp.o
cvararg.o
fileio.o
hello.o
mycpp.o
rangesupport.o
sys.o
testiotransfer.o
wr.o

* also:

integer.x0-integer_m2.cpp
integer.x1-integer_m2.cpp
integer.x2-integer_m2.cpp
integer.x3-integer_m2.cpp
integer.x4-integer_m2.cpp
integer.x5-integer_m2.cpp
