Hi Mike, all,
Following your commit 96bc16f, merged yesterday, my amdgcn toolchain
fails to build. The Newlib built itself completes successfully, but
subsequent use of the library is broken.
The problem seems to be related to the __malloc_lock function, but I
can't quite work out why. Here's the error message:
ld: error: duplicate symbol: __malloc_lock
>>> defined at mlock.c:42 (..../newlib/libc/stdlib/mlock.c:42)
>>> libc_a-mlock.o:(__malloc_lock) in archive

>>> libc_a-malloc_support.o:(.text+0x438) in archive
..../install/amdgcn-amdhsa/lib/libc.a
collect2: error: ld returned 1 exit status
(I should mention that the amdgcn port uses the LLVM binary utilities,
so the error messages look a little different to GNU ld. I've also
elided the long pathnames with "....".)
Previously only the machine-specific __malloc_lock was used, which is of
course the one I want.
Should those functions be added differently now?
Thanks
Andrew

looks like amdgcn doesn't have a GNU port at all, so i can't really repro
this situation. i can't explain why it changed. it might be the overall
ordering changed because of assumptions in the build ...

i think you should always use the same name output if you want to override
regardless of my recent change. the common code defines this in mlock.c,
so i would expect you to put your machine overrides in a mlock.c file in
your machine dir.
this is how all the setjmp, mem*, and str* funcs all work.

OK, I've confirmed that this patch fixes it.
I don't believe I have the power to commit it myself.

amdgcn: Fix build failure
The recent makefile reorganization broke the amdgcn port by creating
duplicate __malloc_lock symbols. This patch fixes the problem by renaming
the malloc_support.c file to mlock.c, thus overriding the default symbol
properly. Actually, I'm not sure how this ever worked?
