[Bug gas/12296] cortex-m3: SVC is not permitted on this architecture

This is indeed the case. Mistake on my part when creating the initial patch.

[Bug gas/12618] Can't resolve difference between symbol and start of its own section
http://sourceware.org/bugzilla/show_bug.cgi?id=12618 rsand...@nildram.co.uk changed: What|Removed |Added CC||rsandifo at nildram dot ||co.uk --- Comment #1 from rsandifo at nildram dot co.uk 2011-03-30 19:09:09 UTC --- I think the new behaviour is correct, and is a deliberate bug fix from earlier binutils. strcmp is defined as an indirection function, so it's address can only be determined at run-time (by calling the strcmp defined here to get the real address). It therefore isn't correct to resolve "strcmp - .text" at assembly time (or link time). The test case wants to refer to the locally-defined strcmp function, so it should use a local label instead of the ifunc symbol. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils

[Bug ld/12608] TLS relocations issues on alpha

Additionally, .o files are only differing in this places
$ cmp --verbose source-ev{4,5}.o

872 42 247
875 175 35
876 247 42
8409 44 50
8433 50 44
$
This actually do not exactly much my understaning relating object code and this
numers (they do not much when doing, hex<->dec, but I will blame cmp reporting
in strange way). Here is the same file piped thru hd, and then compared.

PS. Ah, sorry, cmp --verbose, output in base-8. Now it matches.
This is what I got in resulting .so file in my case (remember binutils 2.18),
$ hd tst-tlsmod7-z-ev4.so | grep '75 23' -A 2

After locating it in objdump -d, I have this

for both ev4 and ev5 .so. This matches a result of Aurelien's ev4.so
I will try bissecting problem.
