Решил попробовать Вашу сборку под винду.
Не находит либу: libc_nano.a

Вы по идеологическим причинам их не собираете?

Так невозможно сравнить Вашу сборку со сборками с ланчпада...

А вообще проект компилируется нормально, но не собирается.

уберите ключик или в спеках поправьте чтобы собиралось с libc

I can confirm you that newlib-nano is now integrated in the main newlib source tree.
Building newlib-nano is now a matter of specifying the right configure option.

This toolchain is released with two prebuilt C libraries based on newlib:
one is the standard newlib and the other is newlib-nano for code size.
To distinguish them, we rename the size optimized libraries as:

libc.a --> libc_s.a
libg.a --> libg_s.a

To use newlib-nano, users should provide additional gcc compile and link time
option:
--specs=nano.specs

At compile time, a 'newlib.h' header file especially configured for newlib-nano
will be used if --specs=nano.specs is passed to the compiler.

Nano.specs also handles two additional gcc libraries: libstdc++_s.a and
libsupc++_s.a, which are optimized for code size.

For example:
$ arm-none-eabi-gcc src.c --specs=nano.specs $(OTHER_OPTIONS)

уверяю Вас что если я соберу с оптимизацией не по скорости а по размеру - НЕнано может оказаться меньше...
Вам размер кода важен? для такого случая собираю редко с ключами -Os и соответсвующими дефайлами всю сборку.

Не тот же косяк, как можно в простынях что я привел увидеть, ключик с параметрами оптимизации у меня передается линкеру как положено. И у меня на ланчпадовских версиях всё нормально.

С Вашими версиями такую проблему (с ненайденными sqrt/sqrtf, memset и так далее) уже встречали и Вы успешно её решали (сообщения в районе 16 октября 2016 года) - https://electronix.ru/forum/index.php?showt...t&p=1455926

Выяснилось, что Launchpad-овская версия скомпилила DSP часть моего проекта в код (Cortex-M7) приблизительлно в полтора раза более шустрее выполняющийся, чем это получилось у klen-gcc (Сообщение #1224).
Предварительно могу сказать что скорее всего виноваты те части libm, которые выполняют logf, powf. CMSIS библиотека не используется.
Ключи ниже в цитате:

То что собирается я еще Jan 13 2017, 21:52 сказал. С ланчпадом работает быстрее. Просто возьмите их параметры сборки - они же выложили.

также до кучи то чем это собиралось

таргет/хост win64

А реально этим пересобрать arm-none-gdb? Хочу собрать с этим https://bugs.launchpad.net/gcc-arm-embedded/+bug/1566054 патчем.

Да, боьшой проект под Cortex-M7 последней сборкой собрался без проблем, отладчик в связке с VSCode из этой сборки работает лучше, чем из arm-none-eabi (тот несколько раз просто вылетал, оставляя за собой stackdump )

собрался это понятно..

а скорость? по сравнению с *-none-*

Разобрался, собрал. С lto cборка ZINGIBER медленнее почти в 3 раза...

Как разобрался?

какая версия "стандартного" компиллера?
соберу и погоняю, посмотрю разницу , поковыряюсь.

8.0.0 намного быстрее компилирует, раза в четыре наверное.

Кстати обнаружил причину странного поведения -flto. Если задать вместе с -flto генерацию отладочной информации (-g), то что-то ломается и lto не работает (об этом есть намек в доках, собственно когда его увидел и решил проверить). Пересобрал ради интереса проект компилятором 7.0.1 (от klen) еще раз без -g, теперь разница со "штатным" GCC около 10%, по прежнему в пользу "штатного" 6.3.1.

а в качестве эксперемента можете подсунуть "руками" memset/memcpy/memmove? чтоб результат погдядеть...

я к счастью ничем внешним не пользуюсь, даже libc и libm свои "местные" в исхниках, в связи с чем никакие либы кроме libgcc самого компиллера в проект не линкуются

klen@ubuntu:/opt/arm-kgp-eabi-8/lib/gcc/arm-kgp-eabi/8.0.0$ arm-kgp-eabi-objdump libgcc.a -t | grep memset
00000000 *UND* 00000000 memset
klen@ubuntu:/opt/arm-kgp-eabi-8/lib/gcc/arm-kgp-eabi/8.0.0$ arm-kgp-eabi-objdump libgcc.a -t | grep memmov
klen@ubuntu:/opt/arm-kgp-eabi-8/lib/gcc/arm-kgp-eabi/8.0.0$ arm-kgp-eabi-objdump libgcc.a -t | grep memcpy
00000000 *UND* 00000000 memcpy
00000000 *UND* 00000000 memcpy
klen@ubuntu:/opt/arm-kgp-eabi-8/lib/gcc/arm-kgp-eabi/8.0.0$

проверил у себя - в libgcc нет этих функций в libgcc.

у меня работает, у Вас нет - а где разница, вот в чем вопрос..

все это подозрительно...

прикольнинько! он тупо заглушку вставил халявщик!
идей море, будем их исключать.

.LVL0:

49 000e 10BD pop {r4, pc}

шаг номер нуль.
я компиляю либу со всеми mem* функциями и Вы пробуете ее линкануть - смотрим реакцию системы, далее следующий шаг. моя гипотеза - уши вылезут в итоге из заголовочных файлов - я думаю компилятор видит код тупо выполняет приказ заменить заглушкой, задача найти это место.
