Hi all: I have something wired and I have no idea whether it comes with elf32-littlemips and elf32-tradlittlemips these 2 different mips link format. 1. I have 2 mips-toolchains, tool A, one support elf32-tradlittlemips with gcc 3.4.4, and, tool B, generated by cross-ng which support elf32-littlemips with gcc4.2.1. 2. I compile my test program with these 2 toolchain with "-c -g " option, and i can see source codes embedded in *.o, the elf output I build. 3. but after I use linker to link them together, I can see the source codes embedded in the final ELF output with tool A build, but tool B cannot. I know the version of these toolchains is quite different, 4.2.1 vs 3.4.4. But everything seems fine before final linking, and the parameters i pass to ld are the same, except the output format they support. Is there any document or steps can tell me how to generate binutils which supports elf32-tradlittlemips such that I can do the comparison, since i cannot see any setting about these 2 format in ct-ng menuconfig. I attach my result and commands at the end of letter for your reference. appreciate your help, miloody /* source codes not embedded in the elf*/ 80000298 <main>: 80000298: 27bdffd8 addiu sp,sp,-40 8000029c: afbf0024 sw ra,36(sp) 800002a0: afbe0020 sw s8,32(sp) 800002a4: 03a0f021 move s8,sp 800002a8: 24020017 li v0,23 800002ac: afc20018 sw v0,24(s8) 800002b0: 24020020 li v0,32 800002b4: afc20014 sw v0,20(s8) 800002b8: 2402002c li v0,44 800002bc: afc20010 sw v0,16(s8) 800002c0: 8fc30018 lw v1,24(s8) 800002c4: 8fc20014 lw v0,20(s8) 800002c8: 00621821 addu v1,v1,v0 800002cc: 8fc20010 lw v0,16(s8) 800002d0: 00621021 addu v0,v1,v0 800002d4: afc20018 sw v0,24(s8) 800002d8: 24040100 li a0,256 800002dc: 0c0000d8 jal 80000360 <malloc> 800002e0: 00000000 nop 800002e4: afc2001c sw v0,28(s8) 800002e8: 0c00009e jal 80000278 <newline> 800002ec: 00000000 nop 800002f0: 03c0e821 move sp,s8 800002f4: 8fbf0024 lw ra,36(sp) 800002f8: 8fbe0020 lw s8,32(sp) 800002fc: 27bd0028 addiu sp,sp,40 /*source code is embedded in elf*/ int main() //int c_entry() { 90: 27bdffd8 addiu sp,sp,-40 94: afbf0024 sw ra,36(sp) 98: afbe0020 sw s8,32(sp) 9c: 03a0f021 move s8,sp char * point; int a,b,c; a =23; a0: 24020017 li v0,23 a4: afc20018 sw v0,24(s8) b = 32; a8: 24020020 li v0,32 ac: afc20014 sw v0,20(s8) c = 44; b0: 2402002c li v0,44 b4: afc20010 sw v0,16(s8) a = a+b+c; b8: 8fc30018 lw v1,24(s8) bc: 8fc20014 lw v0,20(s8) c0: 00621821 addu v1,v1,v0 c4: 8fc20010 lw v0,16(s8) c8: 00621021 addu v0,v1,v0 cc: afc20018 sw v0,24(s8) /*my commands that I can see source */ mipsel-unknown-elf-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -D_ASSEMBLER_ -c init.S mipsel-unknown-elf-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -D_ASSEMBLER_ -c reset.S mipsel-unknown-elf-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -c atexit.c mipsel-unknown-elf-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -c main.c mipsel-unknown-elf-ld -T ./link.xn -o TestCode.elf -Map TestCode.map --oformat elf32-littlemips init.o reset.o atexit.o main.o -static -nostdlib -L/media/sdb1/newlib-1.17.0/build/mipsel/lib -L/root/bare_metal/x-tools/mipsel-unknown-elf/lib/gcc/mipsel-unknown-elf/4.2.4 -lc -lnullmon -lgcc rm -f TestCode.dla rm -f TestCode.dnm /* commands that I cannot see source sde-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -D_ASSEMBLER_ -c init.S sde-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -D_ASSEMBLER_ -c reset.S sde-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -c atexit.c sde-gcc -g -G 0 -mips32r2 -fno-omit-frame-pointer -fno-optimize-sibling-calls -I./include -I./device/display -I./device/fatfs -I./device/misc -I./device/ntstrg -I./device/ntuart -I./device/ntxsub -I./device/vpu -I/media/sdb1/newlib-1.17.0/build/mipsel/include -c main.c sde-ld -T ./link.xn -o TestCode.elf -Map TestCode.map --oformat elf32-tradlittlemips init.o reset.o atexit.o main.o -static -nostdlib -L/media/sdb1/newlib-1.17.0/build/mipsel/lib -L/root/bare_metal/x-tools/sde/lib/gcc/3.4.4/el -lc -lnullmon -lgcc rm -f TestCode.dla -- For unsubscribe information see http://sourceware.org/lists.html#faq
