Problems to select input-section for objectfile(.txt) within linker script file

["Duemer, Karl Heinz" <karlheinz.duemer@xxxxxxxxxxx>]

Hello,
 
I am trying to link the (.txt) sections of some object-files to defined locations, but I am not able to select them within the linker script file.
 
I use mips64-linux-gnu-gcc  in the Version 3.4.3.
 
A simple example includes two very simple c-files h1.c and h2.c.
The compiler commands are:
 
mips64-linux-gnu-gcc -O0 -g -EB -mabi=64 -march=rm9000 -mno-abicalls -fno-pic -Wa,-ahl=h1.lst -o h1.o  -c h1.c
mips64-linux-gnu-gcc -O0 -g -EB -mabi=64 -march=rm9000 -mno-abicalls -fno-pic -Wa,-ahl=h1.lst -o h2.o  -c h2.c
 
The Linker command is:

mips64-linux-gnu-gcc -Tscript.ld  -EB -mabi=64 -march=rm9000 -nostdlib -e main -Wl,-M -Wl,-Map=h12.map  -o h12 h1.o h2.o
 
The linker-script script.ld starts with:
 
OUTPUT_ARCH(mips)
SECTIONS
{
  .text 0xffffffff80100000 :
  {
    h1.o(.txt)
    . += 100;
    h2.o(.txt)
    CREATE_OBJECT_SYMBOLS
  }
 .....
 
The h12.map file shows the problem: 
     The (.txt) sections are not fetched as requestet (gap of 100 bytes between the two parts).
     The input-section directives h1.o(.txt) and h2.o(.txt) are recognized, but ignored...
     The real (.txt) sections are linked after the gap of 100 bytes.
...
Linker script and memory map
 
LOAD h1.o
LOAD h2.o
 
.text           0xffffffff80100000       0xf0
 h1.o(.txt)
                0xffffffff80100064                . = (. + 0x64)
 *fill*         0xffffffff80100000       0x64 00
 h2.o(.txt)
 CREATE_OBJECT_SYMBOLS
 *fill*         0xffffffff80100064        0xc 00
 .text          0xffffffff80100070       0x50 h1.o
                0xffffffff80100070                main
 .text          0xffffffff801000c0       0x30 h2.o
                0xffffffff801000c0                h2
 
The selection of self-defined section in assembler modules works fine.
Example: h3.o(unmapped_uncached) for a an assembler-module h3.o including the line:  .section unmapped_uncached
 
 
My target is:
 
We have a a mix of assembler, C and Chill-SW. The chill linker delivers no ELF-Debug-Information.
I want to derive the debug-info for assembler and C from a gcc-output without Chill-SW (only dummies), but with the 'right' addresses for C and assembler code.
 
 
 
many greetings from
