主题中讨论的其他器件：TMS570LC4357

在 TI Arm Clang 编译器工具用户指南 v1.3中、将 4.1.8更详细地介绍。库命名惯例部分似乎是 ARM 优化 C/C++编译器 v20.2.0.LTS 用户指南中第7.1.8节"库命名惯例"的副本

但是、TI Arm Clang 编译器 ti-cgt-armllvm_1.3.0-beta.1似乎使用的命名约定与 TI Arm Clang 编译器工具用户指南 v1.3中所述的命名约定不同。例如

TI-CGT-armlvm_1.3.0-beta.1使用库文件的.A 后缀、而不是用户指南中描述的.lib 后缀。
TI-CGT-armlvm_1.3.0-beta.1使用单独的目录来编译使用不同选项的运行时库、而不是用户指南中所述库中的不同文件名组件。

是否有关于 TI Arm Clang 编译器库名称惯例与 TI / GCC ARM 工具链比较的说明？

提出问题的原因是很想了解 TI Arm Clang 是否支持 Cortex-R5大端字节序、因为封装的 GCC ARM 编译器不包含大端字节序运行时间库(例如、请参阅 TMS570LC4357：CCS/TMS570LC4357：使用 ARM 编译器9.3-1)

虽然 TI Arm Clang 编译器工具1.3.0.0-beta.1版本说明显示支持"Cortex-R5 (Thumb)与 VFPv3D16"、但如果在 CCS 10.3.0中为 TMS570LC4357创建项目并选择 ti-cgt-armllvm_1.3.0-beta.1、则会失败并显示错误、指示不支持大端字节序目标：

切斯特、您好！

正确的做法是、第4章中的 TI Arm Clang 编译器用户指南中的内容当前基于第7章中的 ARM 优化 C/C++编译器用户指南中的内容。我们正在审查和更新即将发布的 LTS 之前的用户指南中的信息。

对于有关支持大端字节序与 Cortex-R5F 的具体问题、tiarmclang 确实提供了该支持。

除了"-mbig-endian"选项、还应在 tiarmclang 编译命令中包含"-mcpu=cortex-r5 -mfloat-abi=hard -mfp=vfpv3-D16"选项。如果您要在 CCS 上编译工程、可以通过 CCS 编译设置用户界面设置这些选项。

您可以在 tiarmclang 用户指南随附的入门指南(第6节)中找到有关支持哪些 Arm 处理器变体以及选择这些变体的选项的更多详细信息。

关于 tiarmclang 工具链安装中包含的运行时库的命名约定和位置...

正确的是、tiarmclang 运行时库的文件扩展名是".a"。对于 tiarmclang 工具链中支持的每个 Arm 处理器变体、有以下运行时库：

libc.a

libsysbm.a

libsys.a

libclang_rt.builtins.a

libclang_rt.profile.a

libc++.a

libc++ABI

您可以在中找到这些文件的库信息文件版本 /lib。库信息文件提供了库的可用处理器特定版本的索引。例如、libc.a 库信息文件包含指向 libc.a 库的 Cortex-R5F 大端版本的索引、该版本指向其在安装中的位置： /lib/armv7reb-ti-none-eabihf/c/libc.a

如《入门指南》(第2节)中所述、从 tiarmclang 命令行链接时、tiarmclang 将通过--start-group/--end-group 链接器选项在链接中隐式包含运行时库列表：

--start-group -llibc++.a -llibc++abi.a -llibc.a -llibsys.a
 -llibsysbm.a -llibclang_rt.builtins.a -llibclang_rt.profile.a --end-group 

对 libc.a 的引用将在链接时解析为 C 运行时库的相应特定于处理器的版本。 

希望这对您有所帮助。

在 CCS 10.3中使用 TI Clang v1.3.0-beta.1创建的附加工程具有一些 C++代码和两个编译配置：

DEBUG_NO_exceptions 已禁用异常、并且链接和运行正常。

2. debug_exceptions 在编译器选项中启用了-fxceptions。 main.cpp 中针对#ifdef _exceptions 进行了条件编译、以进行简单的异常测试。这会生成有关未解析符号的链接器错误：

当 CCS 编译为链接调用 tiarmclang 时、传递-fexceptions、但链接器似乎不会解析具有异常支持的 C++运行时库。

不确定是创建工程时出错、还是运行时库选择中出现错误。

我可以尝试解决构建配置的链接器错误、但有例外情况。

首先添加了以下库作为输入：

$｛cG_tool_search_path｝/armv7reb-ti-no-eabihf/c++/except/libc ++ABI

$｛cG_tool_search_path｝/armv7reb-ti-no-eabihf/c++/except/libunwind.a

它解析了异常的初始未解析符号、然后得到：

可以通过在链接器命令文件中添加以下符号别名来修复未解析的符号__exidx_start 和__exidx_end：

    .ARM.exidx  align(32) :
    {
     	__exidx_start = __TI_UNWIND_TABLE_START;
		__exidx_end = __TI_UNWIND_TABLE_END;
    } > FLASH0 | FLASH1

但这仍然会留下以下链接器错误、这似乎是由于具有不同浮点支持设置的异常库所致：
