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...

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...
I am using the lm function in R to fit several linear models to a
fair-sized dataset (~160 collections of ~1000 data points each). My
data have intrinsic, systematic uncertainty much greater than the
measurement errors on any individual point. My thought is to use the
residuals of my linear fits to quantify this intrinsic uncertainty, but
I am puzzled over the correct interpretation of R's

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
