For me, C, i.e., GCC, is most useful as a faster way to generate assembly for a particular CPU than typing it out from scratch. I use GCC as a code generator. I'd like to see more free asm code generators, but I am not holding my breath.
I do appreciate C as a medium for distributing reasonably efficient software.
1. Write some C
2. Dump the corresponding assembly code
3. Modify the code by hand
5. Load into assembly debugger
6. Learn
There is "C", the language, which can be relatively simple. Or hopelessly opaque depending on the author.
I think of C the language as just a shorthand for assembly. Only because that's how I use it.

But then there is "C" in practice: the specifications, the "standard" libraries, preprocessors, Makefiles, autoconf, etc.
1. Program that reads some input (e.g., C language) and generates asm and/or opcodes.
2. Program that reads asm and/or opcodes and generates binary numbers ("object files").
So, back in the day (and still for me, always):
assembler: ASCII source code in assembler language -- "which language did you code that in? - Assembler."
assembler: the integrated development environment (such as ASM-One) which produces executable machine code straight from source, with no linking step in-between; also known as a two-pass optimizing assembler.
No. 1 is a program that accepts input (e.g., RTL, MINIMAL, etc.) and generates asm.
I like to call this an asm code generator. Because today when people say "compiler" they are often referring to a collection of programs, some of which do not generate asm.
When I use that term I envision simple filters that take ASCII input, maybe even some sort of "template", and transform it into some other format that's useful. Ideally, asm. But not always.
For example, in GCC, for x86, there's a couple of programs that operate on i386-opc.tbl and i386-reg.tbl. I would not call them "code generators" but I suspect they are needed in order for "gcc -s" to work.
