Hi all,
GCC has startfile and endfile spec string built into it.
startfile is used to specify objects files to include at the start of the link
process.
While endfile, on the other hand, is used to specify objects files to include
at the end
of the link process.
crtbegin.o is one of the object files specified by startfile spec string. IIUC,
crtbeginS.o should be used in place of crtbegin.o when generating shared
objects.
The same applies to crtend.o which is one of the endfile. crtendS.o should be
used when
generating shared objects.
This patch makes the change to use different crtbegin and crtend files when
creating
shared and static object for elf toolchain. The linux toolchain already did this
differentiation.
So when the toolchain doesn't support shared object, the following error
message will be
produced:
ld: cannot find crtbeginS.o: No such file or directory
Still, those specs strings built into GCC can be overridden by using
-specs=command-line switch to specify a spec file.
arm-none-eabi regression test without new issues, OK for trunk?
