The _fdata symbol in MIPS linker scripts is aligned to a 16-byte boundary. The ALIGN function does not implicitly update current location counter. If sections positioned after the assignment do not have the same natural alignment as the ALIGN function then the start of the section group will not coincide with the value of the symbol. Given the linker command sequence: symbol = ALIGN (NN); (.section*) where the idiom implies a desire to mark the beginning of .section with symbol, there must be an assignment to the location counter between the assignment to symbol and the .section pattern. libgloss/ * mips/array.ld: Update the location counter to match _fdata. * mips/cfe.ld: Likewise. * mips/ddb-kseg0.ld: Likewise. * mips/ddb.ld: Likewise. * mips/dve.ld: Likewise. * mips/idt.ld: Likewise. * mips/idt32.ld: Likewise. * mips/idt64.ld: Likewise. * mips/idtecoff.ld: Likewise. * mips/jmr3904app-java.ld: Likewise. * mips/jmr3904app.ld: Likewise. * mips/jmr3904dram-java.ld: Likewise. * mips/jmr3904dram.ld: Likewise. * mips/lsi.ld: Likewise. * mips/mti32.ld: Likewise. * mips/mti64.ld: Likewise. * mips/mti64_64.ld: Likewise. * mips/mti64_n32.ld: Likewise. * mips/nullmon.ld: Likewise. * mips/pmon.ld: Likewise. * mips/sde32.ld: Likewise. * mips/sde64.ld: Likewise.
