2022-02-11Unify core passesAlexey Neyman1-1/+1
With libc_headers step before pass-1, there is no need to distinguish pass-1 and pass-2; they are configured identically (note that with the current configuration, core pass-2 is only used for win32 - hence, uses build_libgcc=yes and mode=static). Signed-off-by: Alexey Neyman <stilor@att.net>
2022-02-11Fold libc_start_files into libcAlexey Neyman7-335/+79
After 557b9d4, libc_start_files and libc_main steps are performed one after another. It doesn't make sense, especially since some of the libcs (glibc, uClibc-ng) go to great lengths to first install start files in the first step, libc_start_files, only to remove them immediately in the second step, libc_main. Current build steps also break in the xtensa newlib configurations, as it needs to install the custom xtensa headers before building the libgcc and after 557b9d4, the headers are not installed before libgcc is built in pass-1. Therefore, finish what 557b9d4 mentioned but did not do: move header installation into a new step, libc_headers, and combine libc_start_files and libc_main into a single step. This also allows to combine the core pass-1/pass-2 steps, to be done in a subsequent commit. Signed-off-by: Alexey Neyman <stilor@att.net>
2022-02-11Retire obsoleted milestonesAlexey Neyman2-41/+23
... and the code dependent on them, after the latest wave of obsolete package removals. This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>
2021-06-24Fix build of older Glibc using GCC >=10Nik Konyuchenko1-0/+4
Issue #1535 GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30. This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10. This change also adds additional cflags for the target GLibc to disable new GCC11 checks that lead to compilation errors. Signed-off-by: Nik Konyuchenko <spaun2002mobile@gmail.com>

2020-10-05glibc: set glibc build system default_cflags emptyHans-Christian Noren Egtvedt1-0/+2
By setting glibc build system default_cflags to be empty before building, we will enforce the build system to only use the crosstool-ng CFLAGS when building glibc. Properly solves the issue identified in #1396. Signed-off-by: Hans-Christian Noren Egtvedt <hegtvedt@cisco.com>

I was trying to build static binaries for a range of Broadcom soft-float ARMv7 SoCs and kept getting SIGILL, although I was targeting Cortex A7 (and A5, later), even on A9 and A15.

2018-12-01Add moxiebox as a choice for libcAlexey Neyman9-137/+163
This required some rework of the libc selection, as moxiebox is a layer on top of another libc - newlib. Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox needs from libcrypto is SHA256, and it already includes a standalone implementation of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use that implementation for the host binary, too. Also, automate collecting/printing the list of all packages in a given category (e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given category.

2017-09-03Super-H multilib toolchain fixesAlexey Neyman1-2/+2
1. On SuperH, configuring GCC with explicit variant of the CPU (like "sh4") limits the default set of multilibs to just that CPU and requires --with-multilib-list to change. Allow for "unspecified" variant, so that we can defer to GCC to determine the list. 2. Support toolchains with both endiannesses at the same time. 3. Add a SuperH/newlib sample 4.
