Added cross-compiler to $PATH in continuous-build.sh
and enabled sudo in .travis.yml.
NOTES:
- travis is unable to update submodules pointing to commits out of their master branch,
so if you push to devtools, you need to push into master branch or your build will be broken
- travis caches conflicts with submodule managements, so we use tmp/toolchain instead of
hacking/cross/toolchain in .travis.yml and continuous-build.sh will mv binaries as required.
Note that libc is what distinguish "native" software from "non-native"
in Jehanne: further C libraries can be ported to Jehanne, but this libc
will remain the main building block of the system.
Also note that a few files have not been ported from Harvey:
- 9sys/pushtls.c
- port/rijndael.c
- port/rijndael.tbl
- port/sha2.c
Pushtls.c depends on libmp and libsec so libc is not the appropriate place
for it. The other three will be moved to libsec.
PRO MEMORIA: in arch/amd64/include/ureg.h the commented registers are preserved.
They were removed at 6ab2e16c9f
but apparently the es register is used by vesavga (386 version) in both Plan9, 9front and 9atom.
