From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Fri, 7 Jan 2000 14:51:19 -0800 (PST) Message-Id: <200001072251.OAA13463@sade.ddi.com> From: Jim Terman MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: linuxppc-dev@lists.linuxppc.org Subject: problem with short in va_arg list with 2.95.1 gcc Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I am having a problem with code that looks for type short in a va_arg list when optimization is turned on. There is no problem with no optimization. It compiles fine but produces an undefined reference to `__va_arg_type_violation' which I assume is delibrate to flag an error. Is there a workaround besides turning off optimizations? If I compile the following file: test.c ------ #include #include void printout(short d, ...) { va_list arglist; printf("%d ", d); d = va_arg (arglist, short); while (d) { printf("%s ", d); d = va_arg (arglist, short); } } int main() { printout(1, 2, 0); printout(2, 3, 4, 0); return 0; } with the command line: > gcc -v -O test.c Reading specs from /usr/lib/gcc-lib/ppc-redhat-linux/2.95.1/specs gcc version 2.95.1 19990809 (prerelease) /usr/lib/gcc-lib/ppc-redhat-linux/2.95.1/cpp -lang-c -v -D__GNUC__=2 -D__GNUC_MINOR__=95 -DPPC -D__ELF__ -Dpowerpc -D__PPC__ -D__ELF__ -D__powerpc__ -D__PPC -D__powerpc -Acpu(powerpc) -Amachine(powerpc) -D__CHAR_UNSIGNED__ -D__OPTIMIZE__ -D_CALL_SYSV -D_BIG_ENDIAN -D__BIG_ENDIAN__ -Amachine(bigendian) -D_ARCH_PPC -D__unix__ -D__linux__ -Dunix -Dlinux -Asystem(unix) -Asystem(posix) test.c /tmp/ccnguSmk.i GNU CPP version 2.95.1 19990809 (prerelease) (PowerPC GNU/Linux) #include "..." search starts here: #include <...> search starts here: /usr/lib/gcc-lib/ppc-redhat-linux/2.95.1/../../../../ppc-redhat-linux/include /usr/lib/gcc-lib/ppc-redhat-linux/2.95.1/include /usr/include End of search list.
