While compiling kernel modules of 2.6.18 I hit this error. The testcase in
question is attached. This file works all fine with gcc 4.1.2 prerelease. but
GCC 4.2.0 prerelease throws the following error message.
test1.c: In function 'unknown_bootoption':
test1.c:15186: warning: asm operand 2 probably doesn't match constraints
test1.c:15186: error: impossible constraint in 'asm'
To reproduce this compile the attached preprocessed file with -O2 -c compile
time options. This work ok when -O2 is not used.
