[Bug target/18326] New: [4.0 regression] mmix-knuth-mmixware testsuite failure: /execute/20040625-1.c

[hp at gcc dot gnu dot org]

Public note of failure.  The test passed around 2004-10-09 on the 3.4 branch.
With LAST_UPDATED: "Sat Nov  6 19:25:03 GMT 2004" I get:
FAIL: gcc.c-torture/execute/20040625-1.c execution,  -O0
FAIL: gcc.c-torture/execute/20040625-1.c execution,  -O1
FAIL: gcc.c-torture/execute/20040625-1.c execution,  -O2

FAIL: gcc.c-torture/execute/20040625-1.c execution,  -O3 -g
FAIL: gcc.c-torture/execute/20040625-1.c compilation,  -Os

With the message in the .log being for execution:
*** EXIT code 4242
(ordinary status wrapper abort message)
For compilation:
/usr/tmp/ccC3G03C.o(.text+0x30): In function `maybe_next':
20040625-1.c: undefined reference to `__lshrti3'
collect2: ld returned 1 exit status
(the port doesn't support TImode)

For the compiler problem, it does not make sense why there is __lshrti3 there in the first place.

With "Tue Nov  9 00:36:20 UTC 2004" the execution failures are gone,
but the compilation failure at -Os remains, same log message.
(Confirmed, because tested on separate system, with pristine sources.)

See comment in <URL:http://gcc.gnu.org/ml/gcc-patches/2004-11/msg01111.html>
regarding the TImode libcall.  I'm closing this anyway; it's not a testsuite
regression anymore.
