Re: How to write pattern for addition with carry operation

Hello! The 16bit target that i am porting to gcc4.1.2 doesn't have any instructions for 32bit operations. But for addition and subtraction there is addc subc instructions that consider carry bit also. Presently i have patterns for SImode addition and subtraction such that the template will have

4.3.0 and 4.3.1 don't build startfiles (crtXXX.o files)

Seen that 4.3.1 has been released, I tried to build i486-linux-uclibc cross-compiler. It went fine except for the detail that none of crt.o files are found in installation directory after "make install" For comparison, gcc 4.2.1's directory has them: # find -name 'crt*.o' ./lib/gcc/i486-linu

PR 36111 also relevant for 4.3.1

glibc 2.7 fails to build with gcc 4.3.1 (error messages given below). Investigating the error, I stumbled upon PR 36111. Applying the patch from http://gcc.gnu.org/viewcvs/trunk/gcc/ChangeLog?view=markup&pathrev=135221 makes gcc 4.3.1 build glibc OK (and everything else that I tried). Maybe so
