We already have 'QemuTargetInfo' struct which is used
with 'query-target', that should also be used with the
new 'query-targets' command.
We need to add the 'endianness' field to QemuTargetInfo.
Why do we want to expose endianness, and what endianness to
expose? Endianness is a runtime bit state of CPUs. Sometime
this bit is hardwired but that is an implementation detail.
For some targets it's, but for some targets it's not. for example
mips-softmmu.mak
mipsel-softmmu.mak
mips64el-softmmu.mak
mips64-softmmu.mak
mips64el-softmmu.mak
mips64-softmmu.mak
only differ the endianless
If you look at git / mailing list history you'll see I spent more
than a year unifying QEMU endianness. It was too much work for a
single person so we decided to reduce the scope to ARM + MicroBlaze
for single binary and we got MicroBlaze unified. We don't want
an endianness-specific single binary. I'm not sure what you are
trying to build, you didn't clearly explained what is your goal here.
You can find series unifying endianness for MIPS, not merged because
more things need to be addressed and not the priority.
