什么是臂EABI-gcc和臂ELF-GCC之间的区别？
他们都可以编译相同的源$ C $ C为Cortex-M3的弓？
What's the differences between arm-eabi-gcc and arm-elf-gcc?Can they both compile the same source code for cortex-m3 arch?
推荐答案
ARM-ELF-GCC 是旧的工具链支持传统的浮点加速器（FPA）和混合端浮点格式。
arm-elf-gcc is the old toolchain supporting legacy floating-point accelerator (FPA) and the mixed-endian floating-point format.
ARM-EABI-GCC 是工具链支持VFP浮点格式的新geneartion。
arm-eabi-gcc is the newer geneartion of toolchain supporting VFP floating-point format.
我想他们会的编译的同出一源，但后来一个是新的，这样一定是丰富的功能明智的。你想听到什么取决于你对编译的OS /库。工具链，基础库和OS在胳膊去的手臂。他们需要有相同的ABI的。
I imagine they can compile the same source, but the later one is newer so that must be richer feature wise. What you want to hear depends on which OS / libraries you are compiling against. Toolchain, fundamental libraries and OS go arm in arm. They need to have same ABIs.
