There are linker scripts located in ldscript dirrectory of compiller.
But changing them does not affects linking. I've copied them to project
directory and included by the -T command. The data is still get plased
wrong.
The scripts are to large to post them here but the lines with rodata
from mspgcc4 and latest mspgcc20110716 are the same
.rel.rodata :
{
*(.rel.rodata)
*(.rel.rodata.*)
*(.rel.gnu.linkonce.r*)
}
.rela.rodata :
{
*(.rela.rodata)
*(.rela.rodata.*)
*(.rela.gnu.linkonce.r*)
the section of scripts that has been changed significantly is as follows:
for mspgcc4:
MEMORY
{
text (rx) : ORIGIN = 0x4000, LENGTH = 0xbfe0
data (rwx) : ORIGIN = 0x1100, LENGTH = 0x2800
vectors (rw) : ORIGIN = 0xffe0, LENGTH = 32
bootloader(rx) : ORIGIN = 0x0c00, LENGTH = 1K
infomem(rx) : ORIGIN = 0x1000, LENGTH = 256
infomemnobits(rx) : ORIGIN = 0x1000, LENGTH = 256
}
for mspgcc20110716:
MEMORY {
sfr : ORIGIN = 0x0000, LENGTH = 0x0010 /* END=0x0010,
size 16 */
peripheral_8bit : ORIGIN = 0x0010, LENGTH = 0x00f0 /* END=0x0100,
size 240 */
peripheral_16bit : ORIGIN = 0x0100, LENGTH = 0x0100 /* END=0x0200,
size 256 */
infomem : ORIGIN = 0x1000, LENGTH = 0x0100 /* END=0x1100,

infob : ORIGIN = 0x1000, LENGTH = 0x0080 /* END=0x1080,
size 128 */
infoa : ORIGIN = 0x1080, LENGTH = 0x0080 /* END=0x1100,
size 128 */
ram (wx) : ORIGIN = 0x1100, LENGTH = 0x2800 /* END=0x3900,
size 10K */
rom (rx) : ORIGIN = 0x4000, LENGTH = 0xbfe0 /* END=0xffe0,
size 49120 */
vectors : ORIGIN = 0xffe0, LENGTH = 0x0020 /* END=0x10000,
size 32 */
/* Remaining banks are absent */
bsl : ORIGIN = 0x0000, LENGTH = 0x0000
infoc : ORIGIN = 0x0000, LENGTH = 0x0000
infod : ORIGIN = 0x0000, LENGTH = 0x0000
far_rom : ORIGIN = 0x00000000, LENGTH = 0x00000000
}
