Bug ID: 82016
Summary: [8 regression] test case
gcc.target/powerpc/float128-type-1.c fails after
r251260
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
r251260 is the change to wide-int.h but this test case failure is different
from the others that change caused.
The test case states:
/* This test tests whether -mfloat128-type (which enables the underlying IEEE
128-bit floating point) is enabled by default on VSX Linux 64-bit systems,
even if the keywords __float128 and _Float128 (-mfloat128) are not enabled
via the -mfloat128 switch. Test that power8 generates a call to the
__addkf3 emulation function. */
and after the wide-int.h change the call to __addkf3 is missing.
