Hello all, I use gcc which was configured for Mitsubishi m32r. I found that gcc generate wrong code, which compiled with -O2. Without Optimization, gcc generates code, correctly. ------ system ------ FreeBSD 4.5-RELEASE - gcc configuration - Configured with: ../gcc-3.2.2/configure --target=m32r-unknown-elf --with-gnu-as --with-gnu-ld --enable-languages=c Thread model: single gcc version 3.2.2 -------------------- Sample source code. ---- m32r_bug.c ---- static int f( int a ) { int b; b = 0; if (a != 0) b = 1; return b; } -------------------- ./xgcc -B./ -O2 -S m32r_bug.c -o m32r_bug.s -------------------- Output code. ---- m32r_bug.s ---- .section .text .balign 4 .type f,@function f: ; PROLOGUE, vars= 0, regs= 0, args= 0, extra= 0 addi r0,#0 ; EPILOGUE jmp lr .Lfe1: .size f,.Lfe1-f .ident "GCC: (GNU) 3.2.2" -------------------- Is there a patch for this problem? --- There is Another problem. When gcc compiles a large size c source code, gcc acts something wrong. But, I have not sample now. thanks for any help tanaka ------ Want more information?
