gcc 9 and 10

Parts before 1997
Before 1997, POSIX comprised several standards:

POSIX.1: Core Services (incorporates Standard ANSI C) (IEEE Std 1003.1-1988)
Process Creation and Control
Signals
Floating Point Exceptions
Segmentation / Memory Violations
Illegal Instructions
Bus Errors
Timers
File and Directory Operations
Pipes
C Library (Standard C)
I/O Port Interface and Control
Process Triggers
POSIX.1b: Real-time extensions (IEEE Std 1003.1b-1993, later appearing as librt—the Realtime Extensions library)[9])
Priority Scheduling
Real-Time Signals
Clocks and Timers
Semaphores
Message Passing
Shared Memory
Asynchronous and Synchronous I/O
Memory Locking Interface
POSIX.1c: Threads extensions (IEEE Std 1003.1c-1995)
Thread Creation, Control, and Cleanup
Thread Scheduling
Thread Synchronization
Signal Handling
POSIX.2: Shell and Utilities (IEEE Std 1003.2-1992)
Command Interpreter
Utility Programs

Versions after 1997
After 1997, the Austin Group developed the POSIX revisions. The specifications are known under the name Single UNIX Specification, before they become a POSIX standard when formally approved by the ISO.

POSIX.1-2001 (with two TCs)

POSIX.1-2001 (or IEEE Std 1003.1-2001) equates to the Single UNIX Specification version 3.[10]

This standard consisted of:

the Base Definitions, Issue 6,
the System Interfaces and Headers, Issue 6,
the Commands and Utilities, Issue 6.

IEEE Std 1003.1-2004 involved a minor update of POSIX.1-2001. It incorporated two minor updates or errata referred to as Technical Corrigenda (TCs).[11] Its contents are available on the web.[12]

POSIX.1-2008 (with two TCs)

Base Specifications, Issue 7 (or IEEE Std 1003.1-2008, 2016 Edition) is similar to the current 2017 version (as of 22 July 2018).[13][14]

This standard consists of:

the Base Definitions, Issue 7,
the System Interfaces and Headers, Issue 7,
the Commands and Utilities, Issue 7,

the Rationale volume.POSIX.1-2017

IEEE Std 1003.1-2017 (Revision of IEEE Std 1003.1-2008) - IEEE Standard for Information Technology—Portable Operating System Interface (POSIX(R)) Base Specifications, Issue 7 is available from either The Open Group or IEEE and is, as of 22 July 2018, the current standard. It is technically identical to POSIX.1-2008 with Technical Corrigenda 1 and 2 applied. A free online copy may still be available.[13]

I mean, did i understand right, that sba/adtools is the latest public stuff we got in terms of gcc/binutils

but when it comes to clib2, then what we have on the sba/adtools are outdated stuff, and we can not need to rely on it

ps. Is your mail that ola.soder at axis current one?

--enable-plugin is necessary for gcc-ar, gcc-nm and gcc-ranlib to work, which
must be used with GCC 4.9 for LTO to work.

32 --prefix=/gcc
33 make -C $(NATIVE_BUILD_DIR)

the https://github.com/sba1/adtools/blob/m ... gcc-build/features.mk#L12 is working fine.

Maybe it has to do with my compiling environment. I will investigate more.
