I build my gcc(3.4.4 and 4.0.2) mips-elf cross compile toolchain on my cygwin and fedora core4 with the following configuration: --prefix=/opt/mips-elf-tools --target=mips-elf --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib --with-gxx-include-dir=/opt/mips-elf-tools/mips-elf/include when tested the toolchain with following code: static int x; static int w; static const int y[]={0,1,2,3,4,5,6,7,8,9}; static int zz=10; static void z(void) { w=x; } int xxx(void) { x=y[6]; z(); zz=y[1]; } I tried both -fPIC and -fno-PIC options as follows: mips-elf-gcc -S -fPIC test.c -o test.1.s mips-elf-gcc -S -fno-PIC test.c -o test.2.s but I found -fno-PIC option seem not to be working, mips-elf-gcc just produce PIC code while given the -fno-PIC option anybody can help me with this? many thanks content of test.1.s and test.2.s are as follows: .file 1 "test1.c" .section .mdebug.abi32 .previous .rdata .align 2 .type y, @object .size y, 40 y: .word 0 .word 1 .word 2 .word 3 .word 4 .word 5 .word 6 .word 7 .word 8 .word 9 .section .sdata,"aw",@progbits .align 2 .type zz, @object .size zz, 4 zz: .word 10 .text .align 2 .ent z z: .frame $fp,8,$31 # vars= 0, regs= 1/0, args= 0, gp= 0 .mask 0x40000000,-8 .fmask 0x00000000,0 .set noreorder .set nomacro addiu $sp,$sp,-8 sw $fp,0($sp) move $fp,$sp lw $2,%gp_rel(x)($28) nop sw $2,%gp_rel(w)($28) move $sp,$fp lw $fp,0($sp) addiu $sp,$sp,8 j $31 nop .set macro .set reorder .end z .align 2 .globl xxx .ent xxx xxx: .frame $fp,24,$31 # vars= 0, regs= 2/0, args= 16, gp= 0 .mask 0xc0000000,-4 .fmask 0x00000000,0 .set noreorder .set nomacro addiu $sp,$sp,-24 sw $31,20($sp) sw $fp,16($sp) move $fp,$sp lui $2,%hi(y) addiu $2,$2,%lo(y) lw $2,24($2) nop sw $2,%gp_rel(x)($28) jal z nop lui $2,%hi(y) addiu $2,$2,%lo(y) lw $2,4($2) nop sw $2,%gp_rel(zz)($28) move $sp,$fp lw $31,20($sp) lw $fp,16($sp) addiu $sp,$sp,24 j $31 nop .set macro .set reorder .end xxx .lcomm x,4 .lcomm w,4 ------ Want more information?
