Host system: Windows XP SP3, with Cygwin installed
Compiler: gcc 4.4.2, cross-compiler (configured with ./configure
--target=i586-elf --prefix=/usr/cross --disable-nls --enable-languages=c,c++
--without-headers)
Binutils: 2.20 (configured with ./configure --target=i586-elf
--prefix=/usr/cross --disable-nls)
When compiling some OS development examples, I found that ld does not change the
addresses of constant strings (inside .rodata) after linking multiple object
files with a script. Attached is an example (C source, linker script and
assembler file), with nasm, gcc and ld included.
Steps to reproduce:
- unpack archive
- run build.bat
- examine the resulting krnl.lst (created with objdump, I kept it in the archive
for convenience)
- inside <main>, look at the addresses of strings passed to memcpy (in my case,
they are 0x8048160 and 0x80481a0)
This does not reproduce with MinGW (binutils 2.20).
