In particular, AS_NEEDED ( /lib/ld-linux.so.2 ) is missing in /usr/lib/libc.so, so for TLS using programs which use ___tls_get_addr or other symbols provided by ld.so you need to specify ld.so on the command line explicitly when using -Wl,-z,defs. On newer OSes that is not needed.

How are you configuring glibc? I think that is the problem here.
You should only configure glibc with --prefix=/usr . And then install like:
make install install_root=${MY_PREFIX}/sysroot .

This test program shows the problem: program gformat implicit none real :: pi = 3.1415926535 write(*, '(a,f0.3,a,g0.3,a)') 'f0.3:', pi, ' g0.3:', pi, '' end The results give f0.3:3.142 g0.3:3.14 The relevant part of the F2008 Standard is 10.7.5.2.2 subsection 4.

Still, as dt_parm.1 is clobbered it possibly gets assigned a and by means of being clobbered it will clobber a ... Not sure if we can restrict non-escaping to also not escape to other parameters? Possibly we should, otherwise this property won't be very useful.

One is created by finish_anon_union - build_anon_union_vars during tsubst_expr, but when tsubsting the a = 0; assignment that VAR_DECL is copied to a new VAR_DECL by tsubst_decl. Apparently build_anon_union_vars is called twice, once during parsing, once during instantiation, but all the pushdecls the second time look really weird and don't affect what VAR_DECLs the following code actually uses. I would expect that during tsubst either build_anon_union_vars isn't called at all and instead pt.c somehow adjusts when needed the VAR_DECLs that were already created (after tsubst_decling them), or create a new set of vars, but somehow arrange those to be registered as the local specializations of the old vars. Jason, could you please look at this? Thanks.

[Bug middle-end/53667] [4.6/4.7/4.8 Regression] Cray pointer: Wrong result with optimizations
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53667 --- Comment #6 from Tobias Burnus burnus at gcc dot gnu.org 2012-09-07 09:38:56 UTC --- (In reply to comment #5) Not sure if we can restrict non-escaping to also not escape to other parameters? Possibly we should, otherwise this property won't be very useful. I think that's also what the current setting in Fortran's trans-types.c's create_fn_spec does: It also sets . instead of r or w for TARGET as the pointer address of those can escape via the argument or otherwise. If an argument is neither TARGET nor POINTER, I don't see a way how a pointer can escape. Thus, I think that interpretation makes sense from the Fortran side. (I haven't audited the fn spec for the libgfortran functions, but I think for those the same applies.)

Thanks for the reduced testcase. The innermost loops compare as follows:
4.5:
.L7:
movsd (%rbx,%rcx), %xmm0
addq$8, %rcx
mulsd 0(%rbp,%rdx), %xmm0
addq$8, %rdx
cmpq$24, %rdx
addsd %xmm0, %xmm1
movsd %xmm1, (%rsi)
jne .L7
4.7:
.L13:
movq64(%rsp), %rdi
movq80(%rsp), %rdx
addq%rcx, %rdi
addq%r8, %rdx
movsd -8(%rax,%rdi), %xmm0
mulsd (%rsi,%rax), %xmm0
addq$8, %rax
cmpq$24, %rax
addsd (%rdx), %xmm0
movsd %xmm0, (%rdx)
jne .L13
so we seem to have a register allocation / spilling issue here as well
as a bad induction variable choice. GCC 4.8 is not any better here.

[Bug target/54517] New: wrong inlining of builtin_shuffle on ARM/big-endian
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54517 Bug #: 54517 Summary: wrong inlining of builtin_shuffle on ARM/big-endian Classification: Unclassified Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassig...@gcc.gnu.org ReportedBy: christophe.l...@st.com Created attachment 28146 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28146 testcase As exposed by the attached sample code, GCC for ARM/big-endian produces incorrect code when inlining functions performing builtin_shuffle. Compile the attached program at -O2 with GCC configured for armeb-none-linux-gnueabi) and execute it with qemu-armeb, it should be OK. Then edit the source code such that NOINLINE now expands into the empty string: #define NOINLINE, re-compile execute: the code aborts.
