Re: incorrect alignment in .scommon section
Hi chenpp, mips-elf-gcc -I. -Iinclude -Iproject/S20/conf/main -I -O2 -fno-builtin -nostdinc -fno-delete-null-pointer-checks -EB -mabi=eabi -msoft-float -march=mips32 -c pid.c -o project/S20/build/main/target/S20/uart-init.o This command line just creates the object file. What is the command line that you use to link the object file and create the map file ? 0x000b5cf2test1 <-- unaligned !!! This certainly does appear to be a linker problem. Can you put together a small test case to demonstrate the problem ? I have tried using the information in your previous email, but I could not create an unaligned assignment for test1. (ie I always found that the linker was aligning test1 on a 4 byte boundary, so there must be some difference between my test and yours).

Re: [Bug ld/2607] linker doesn't recognize an ELF library.
Hi Pawel, I will attach the three different shared objects, in the event that some maintainer has access to an appropriate Solaris/Sparc system and can determine what the issue is. Thanks. That has allowed me to locate the problem. The libbug.so.CC file has a section named .exception_ranges which has an link value of 0xFF00. Normally the link value should be a valid index into the section table in the ELF binary, and the BFD library was detecting this discrepancy and treating the file as invalid. The bug however was that certain other special values are allowed in the index field. Namely values in the range of SHN_LOPROC (0xFF00) to SHN_HIOS (0xFF3F). So please could you try out the uploaded patch which I hope will correct the problem. It certainly works for me using libbug.so.CC file that you supplied.
