Understanding of ldd header allocation
...Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x001000 0x80000000 0x80000000 0x08284 0x08284 RWE 0x1000
Section to Segment mapping:
Segment Sections...
00 .text .rodata .eh_frame .data
However, what ldd does is different. (To create a single segment I use --omagic argument, it works fine and is unrelated). The first segment is created at a lower address, with ELF headers in it, and then the actual text section exactly at 0x80000000:
Elf file type is EXEC (Executable file)
Entry point 0x80002670
There are 3 program headers, starting at offset 52

Interpreting lm Residuals...
...it and the residuals to one of my
sub-groups, for illustration. By eye, the overwhelming majority of the
residuals are within +- 0.4, and I would therefore expect the standard
error of the residuals to be ~0.2. However, the output from lm does not
show this:

Call:
lm(formula = omag ~ oper, weights = (1/oerr))

Linking the FreeBSD base system with lld -- status update
...7 libc_nonshared.a libssp_nonshared.a )". ld.bfd includes a
built-in /lib search path and finds /lib/libc.so.7 there. lld relies
only on the -L paths specified on the command line, and cannot locate
libc.so.7. As a workaround I've changed /usr/lib/libc.so to include
the full path.
4. -N/--omagic option
-N makes the text and data sections RW and does not page-align data.
It is used by boot loader components.
5. -dc option
-dc assigns space to common symbols when producing relocatable output
(-r). It is used by the /rescue build, which is a single binary

Compiling for baremetal ARMv4 on Ubuntu Linux
Hello Christian,
I reran my script with a similar cmake command to yours. After the
build finished the following command from the build directory gave me:
find . -name \*builtins.a
./lib/clang/9.0.0/armv6m-none-eabi/lib/libclang_rt.builtins.a
./lib/clang/9.0.0/armv7m-none-eabi/lib/libclang_rt.builtins.a
./lib/clang/9.0.0/armv7em-none-eabi/lib/libclang_rt.builtins.a
I hope you see something like
