  • startup/linkcmds: In support of gcc 3.1, added one of more of the sections .jcr, .rodata*, .data.*, .gnu.linkonce.s2.*, .gnu.linkonce.sb2.*, and .gnu.linkonce.s.*. Spacing corrections and direction of segments to memory regions may also have been addressed. This was a sweep across all BSPs.
  • Property mode set to 100644
