Hi, I had built a set of tools implementing arm-unknown-aout from binutils-2.9.1, newlib-1.8.2 and gcc-2.95.2 and a few patches found on the net. It seems like linker has a bug. I am using following command to build a test program: $(CC) $(CFLAGS) -o tst -nostartfiles -Wl,-e,_start tst.c Test program is below: #include <stdio.h> #define BEFORE 1 #if BEFORE void start(void) { } #endif int main(int argc, char *argv[]) { printf("Hello, world\n"); return 0; } #if !BEFORE void start(void) { } #endif It has OK file header: tst: file format a.out-arm-little tst architecture: arm, flags 0x000001be: EXEC_P, HAS_LINENO, HAS_DEBUG, HAS_SYMS, HAS_LOCALS, WP_TEXT, D_PAGED start address 0x00008000 Sections: Idx Name Size VMA LMA File off Algn 0 .text 00010000 00008000 00008000 00008000 2**4 CONTENTS, ALLOC, LOAD, CODE 1 .data 00008000 00018000 00018000 00018000 2**4 CONTENTS, ALLOC, LOAD, DATA 2 .bss 00000000 00020000 00020000 00000000 2**4 ALLOC However,once I change BEFORE to 0, the file header will beecome tst: file format a.out-arm-little tst architecture: arm, flags 0x000001be: EXEC_P, HAS_LINENO, HAS_DEBUG, HAS_SYMS, HAS_LOCALS, WP_TEXT, D_PAGED start address 0x00008044 Sections: Idx Name Size VMA LMA File off Algn 0 .text 0000ffe0 00008000 00008000 00000020 2**4 CONTENTS, ALLOC, LOAD, CODE 1 .data 00008000 00018000 00018000 00010000 2**4 CONTENTS, ALLOC, LOAD, DATA 2 .bss 00000000 00020000 00020000 00000000 2**4 ALLOC Which is incorrect because text will still be located at offset 0x8000 in the file. So, I am quite puzzled to say the least, is it a known bug ? Thanks, Aleksey ------ Want more information? See the CrossGCC FAQ, http://www.objsw.com/CrossGCC/ Want to unsubscribe?
