I only added MIPS since this target has a fundamental issue with the
TLS
support.
Which target would you also exclude?
About half of them.
It seems to be only bfin, lm32, moxie, or1k, and v850. Are these targets
still in use? Do we have a maintainer for these targets?
arch64 - Yes
arm - Yes
bfin - ?
i386 - Yes
lm32 - ?
m68k - Yes
microblaze - Yes
mips - No
moxie - ?
nios2 -?
nios2 - Yes
or1k - ?
powerpc - Yes
riscv - Probably
riscv - Yes
sh - ?
sparc - Yes
sparc64 - ?
v850 - ?
x86_64 - Likely
I'm not even sure there is a definition of how TLS is implemented
on some of these architectures. Maybe GCC has a generic way of
handling TLS that a port could fall back on, but I am unaware of it.
If we are to maintain a thread safe C Library, then we have to be
sure TLS is always supported or we have to have a fallback
method.
The fallback method for C++ is only thread safe if you have enough POSIX
keys configured.
