如何将 map LTO 部分转换为 GCC（臂）Z3175B42760467807B8873 中的 output 部分

Question

I have a linker file that I use as input for Gnu Arm Embedded Toolchain.

It contains, among other things, an output section like this:

.text :
{
  . = ALIGN(4);
  *(.text*)
  *(.rodata*)
} > FLASH

, where FLASH is a MEMORY block.

My issue is that, when I compile a C++ file with LTO (link-time optimization), some of my code is put in non-".text" sections in the resulting object files. These sections seems to be consistently named:

.gnu.lto<SOMETHING>

As a result, they are not placed in my.text output section.

How can I map LTO input sections to my.text output section?

Answer 1

It turns out my issue was related to a misunderstanding in how the VMA and LMA statements work in GNU linker files. So, in essense the LTO section are mapped correctly. Thanks to anyone who spent time on this.
