Bug ID: 69586
Summary: FAIL: gcc.dg/uninit-21.c for target defaulting to
short enum
Product: gcc

Dump of failing uninit1 pass
Hi,
The new gcc.dg/uninit-21.c fails on arm-none-eabi with the following error:
gcc/testsuite/gcc.dg/uninit-21.c: In function 'yp_update':
gcc/testsuite/gcc.dg/uninit-21.c:31:3: warning: 'master' may be used
uninitialized in this function [-Wmaybe-uninitialized]
FAIL: gcc.dg/uninit-21.c (test for bogus messages, line 31)
The test succeeds if passing -fno-short-enum or giving RPC_CANTENCODEARGS a
value to big to represent with an unsigned short (65536 or higher) due to the
cast creating confusing. See attached dump of uninit1 pass. The second cast
using a bitwise and with 255 starts from forwprop1.
Best regards.
