Bug #: 14950
Summary: Compile error in opcodes/ppc-opc.c (binutils-2.23.1)
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: llew...@raytheon.com
Classification: Unclassified
When cross compiling under cygwin with GCC 3.4.4., two warnings in ppc-opc.c
cause a build failure.
ppc-opc.c: In function `insert_sci8':
ppc-opc.c:1644: warning: comparison between signed and unsigned
ppc-opc.c:1650: warning: comparison between signed and unsigned
Makefile:932: recipe for target `ppc-opc.lo' failed
The offending lines are:
1644 else if ((value & 0xff0000) == (unsigned int)value)
1645 {
1646 scale_factor = 2;
1647 ui8 = value >> 16;
1648 fill = 0;
1649 }
1650 else if ((value & 0xff00) == (unsigned int)value)
The cast to unsigned int makes sense on line 1638 since 0xff000000 will be an
unsigned. But not on lines 1644 and 1650 where both 0xff0000 and 0xff00 are
signed. Changing to the following fixes the problem:
1644 else if ((value & 0xff0000) == value)
1645 {
1646 scale_factor = 2;
1647 ui8 = value >> 16;
1648 fill = 0;
1649 }
1650 else if ((value & 0xff00) == value)
