See http://www.darkcoding.net/software/learning-assembler-on-linux/
Extremely basic Linux x64 assembly. Not really for public consumption. Most of these (except lib) just 'make' in the directory.
-
hello: Write hello world. Exit.
-
caps: Lower-case a string. This has a loop and a test in it.
-
upper: Basic unix text filter. Upper case stdin to stdout.
-
djb2: djb2 hash function. http://www.cse.yorku.ca/~oz/hash.html
-
prt: Exercise lib/WriteHex, which prints number as hex.
-
alloc: Test lib's alloc calls (which use brk). No output, watch it in gdb.
-
allocmmap: Allocate heap memory with mmap. No output.
-
lib: Re-usable macros and procedures
-
cml: Work in progress. Most everything else is notes and experiments to support this.
Debugging with gdb:
- Include
-gstabs+when assembling. - Debug text filters, in gdb:
run < inputfile > outputfile - Show assembly, registers in gdb:
layout regs
