As email archive for the discussion with the title "Change in .ld syntax or a
bug?".
It appears that an empty section does not cause . to be set correctly. This
affects eCos when compiling for the synthetic target which has an empty .vectors
section first with an absolute address. The following sections should follow on,
but since . it incorrect, the following sections are placed in incorrect
addresses where there is no ram.
A test case will be attached soon. Unpack the test case and then go into
directory:
testcase/hal/common/current
In that directory do:
~/pkgs/binutils/build/ld/ld-new -v --eh-frame-hdr -m elf_i386 -dynamic-linker
/lib/ld-linux.so.2 -o context -L../../../install/lib
-L/usr/lib/gcc/i486-linux-gnu/4.0.2 -L/usr/lib/gcc/i486-linux-gnu/4.0.2
-L/usr/lib/gcc/i486-linux-gnu/4.0.2/../../../../lib
-L/usr/lib/gcc/i486-linux-gnu/4.0.2/../../.. -L/lib/../lib -L/usr/lib/../lib
tests/context.o --gc-sections -static -Ttarget.ld
When the bug occurs the following output will occur:
