[Bug bootstrap/16547] New: Tru64 UNIX bootstrap failure: warning compiling mips-tdump.c

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Between 20040618 and 20040709, mainline started to fail bootstrap on Tru64
UNIX (both alpha-dec-osf4.0f and alpha-dec-osf5.1b) due to a warning
compiling mips-tdump.c in stage2:

$ stage1/xgcc -Bstage1/ -B/vol/gcc/share/alpha-dec-osf4.0f/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I. -I/vol/gnu/src/gcc/gcc-dist/gcc -I/vol/gnu/src/gcc/gcc-dist/gcc/. -I/vol/gnu/src/gcc/gcc-dist/gcc/../include -I/vol/gnu/src/gcc/gcc-dist/gcc/../libcpp/include -I/vol/gnu/src/gcc/gcc-dist/gcc/../libbanshee/libcompat -I/vol/gnu/src/gcc/gcc-dist/gcc/../libbanshee -I/vol/gnu/src/gcc/gcc-dist/gcc/../libbanshee/points-to  /vol/gnu/src/gcc/gcc-dist/gcc/mips-tdump.c -o mips-tdump.o

/vol/gnu/src/gcc/gcc-dist/gcc/mips-tdump.c:334: warning: case label value 32 exceeds maximum value for type
make[2]: *** [mips-tdump.o] Error 1

Environment:
System: OSF1 rimsky V4.0 1229 alpha
Machine: alpha
	
host: alpha-dec-osf4.0f
build: alpha-dec-osf4.0f
target: alpha-dec-osf4.0f
configured with: /vol/gnu/src/gcc/gcc-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf4.0f --build alpha-dec-osf4.0f --target alpha-dec-osf4.0f --disable-libmudflap

How-To-Repeat:
Bootstrap mainline as described above.
------- Additional Comments From ro at techfak dot uni-bielefeld dot de  2004-07-14 17:56 -------
Fix:
I can get the bootstrap to finish if I add

mips-tdump.o-warn = -Wno-error

to gcc/Makefile.  Testsuite results
(http://gcc.gnu.org/ml/gcc-testresults/2004-07/msg00673.html) look
reasonable compared to those of 20040618.
