If neither AT(lma) nor AT>lma_region is specified, D76995 keeps `lmaOffset` (LMA - VMA) if the previous section is in the default LMA region. This patch additionally checks that the two sections are in the same memory region. Add a test case derived from https://bugs.llvm.org/show_bug.cgi?id=45313 .mdata : AT(0xfb01000) { *(.data); } > TCM // It is odd to make .bss inherit lmaOffset, because the two sections // are in different memory regions. .bss : { *(.bss) } > DDR With this patch, section VMA/LMA match GNU ld. Note, GNU ld supports out-of-order (w.r.t sh_offset) sections and places .text and .bss in the same PT_LOAD. We don't have that behavior.
