Hi Richard,
I was just trying to build the trunk GCC at r165246
Configured thusly:
$ ../trunk/configure --target=mips64-linux
--with-sysroot=/home/daney/mips64-linux
--prefix=/home/daney/mips64-linux --with-arch=mips64r2
--enable-languages=c --disable-libmudflap
Back on:
r162086 | rsandifo | 2010-07-12 11:53:01 -0700 (Mon, 12 Jul 2010) | 36 lines
gcc/
* doc/tm.texi.in (SWITCHABLE_TARGET): Document.
[...]
You added SWITCHABLE_TARGET, but it seems to break building now in expr.c
gcc -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall
-Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes
-Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros
-Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common
-DHAVE_CONFIG_H -I. -I. -I../../trunk/gcc -I../../trunk/gcc/.
-I../../trunk/gcc/../include -I../../trunk/gcc/../libcpp/include
-I../../trunk/gcc/../libdecnumber -I../../trunk/gcc/../libdecnumber/dpd
-I../libdecnumber -I/usr/include/libelf ../../trunk/gcc/expr.c -o expr.o
In file included from ../../trunk/gcc/expr.c:57:
../../trunk/gcc/target-globals.h:24: error: expected identifier or ‘(’
before ‘&’ token
../../trunk/gcc/target-globals.h: In function ‘restore_target_globals’:
../../trunk/gcc/target-globals.h:63: error: lvalue required as left
operand of assignment
This seems to be caused by:
flags.h:243 #define this_target_flag_state (&default_target_flag_state)
target-globals.h:24 extern struct target_flag_state *this_target_flag_state;
Which when preprocessed we get:
expr.i:??? extern struct target_flag_state *(&default_target_flag_state);
Which evidently is not valid C.
I am not sure how to go about fixing this.
Do you have any ideas?
David Daney
