Prefer -Ttext over linker script values. I found this while trying to build u-boot. It uses -Ttext in combination with linker scripts. My first reaction was to change the linker scripts to have the correct value, but I found that it is actually quite convenient to have -Ttext take precedence. By having just .text : { *(.text) } In the script, they can define the text address in a single Makefile and pass it to ld with -Ttext and for the C code with -DFoo=value. Doing the same with linker scripts would require them to be generated during the build. llvm-svn: 305766
