Add the full crosstool-NG sources to the new repository of its own. You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

# C library options
config/libc: move around hidden config options This yields a cleaner .config file that is easier to read.

Introduce a new EXPERIMENTAL feature: BARE_METAL. This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library. Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal. Move the compiler build script to its own sub-directory. Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal. Update the ARM target tuples to enable bare-metal targets. Add two ARM bare-metal samples.

help
Enter the date of the snapshot you want to use in the form: YYYYMMDD
where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit
day in the month.
Please note:
- glibc has snapshots done every monday, and only the last ten are kept.
- uClibc has daily snapshots, and only the last 30-or-so are kept.
So if you want to be able to re-build your toolchain later, you will
have to save your C library tarball by yourself.
Generate the choice menu for C libraries, the same way arch and kernels are generated. /trunk/kconfig/kconfig.mk | 10 8 2 0 ++++++-- /trunk/scripts/build/libc/glibc.sh | 2 1 1 0 +- /trunk/config/libc/glibc.in | 22 6 16 0 +++++------------- /trunk/config/libc/uClibc.in | 7 6 1 0 +++++- /trunk/config/libc/eglibc.in | 12 11 1 0 +++++++++- /trunk/config/libc.in | 53 4 49 0 +++----------------------------------------- 6 files changed, 36 insertions(+), 70 deletions(-)

Move the whole threading ;odel choice out of glibc and into the generic C library options: even uClibc may have NPTL at one point in the (hopefully near) future. Mark the progress bar as being CPU-intensive. Little style fix to the core C compiler build step.

Move the threading model choice back to the C library menu: - the threading models available are dependent on the C library used - it is thus easier to first select the C libary, and then the threading model, rather going back to the toolchain menu. /trunk/config/toolchain.in | 29 0 29 0 ----------------------------- /trunk/config/libc.in | 47 38 9 0 ++++++++++++++++++++++++++++++++++++++--------- 2 files changed, 38 insertions(+), 38 deletions(-)
