configure does not detect the correct architecture baseline node ARM-Instruction-Set in as.info https://blueprints.edge.launchpad.net/ubuntu/+spec/mobile-lucid-arm-gcc-v7-thumb2.
Arm (32 bit) has two commonly used instruction sets; Thumb2 and Arm. The Arm instructions, while C code compiled via GCC was generating Thumb2 code. to make GHC generate Thumb2 code (which potentially has some performance3 May 2017 The ARM Thumb-2 instruction set is not a new thing. for many applications and also how to configure it in Yocto build system for Linux kernel, The code size with GCC and -O2 optimization level was reduced for common
ARM processors have long supported the 16-bit Thumb instruction set, Several of the samples actually decoded faster with the Thumb-2 build, with the latest CodeSourcery GCC version will generate these instructions with default settings.
22 Apr 2011 Thumb-2 technology is the instruction set underlying the ARM Cortex to compile your applications for Cortex A8/A9 core with GCC,export the
8 Sep 2016 I just found that I should say .syntax unified. below .section. The following topic deals with other things, but I saw it there and tried. It worked.
8 Jun 2011 Building Stand-Alone Assembler Files in Thumb-2 The specification for atomic primitives implemented by GCC can be found here: Thumb 2. no. no. no. no. no. not applicable; ARM instruction set not guaranteed to be
19 Jan 2017 ARM and Thumb-2 instruction sets, and their influences on code generation. Specifically, we look at . ISA allows the programmer to easily make full use of all the architecture’s features. .. This is the approach taken by GCC.
18 Mar 2016 Comparison against GCC. 0 Focus on the Thumb-2 instruction set in this talk Goal: Want to compile with Clang but code size significantly.
Without this option the two instruction sets cannot be reliably used inside one program. The default is -mno-thumb-interwork , since slightly larger code is generated In particular, you need to compile libgcc.a , the library that comes with GCC,
