The following works (thanks to
https://stackoverflow.com/questions/44040235/using-gdb-to-find-exactly-where-the-error-occurs-sparc-assembly):
1. In gdb, "layout asm" runs TUI with the startup code on display.
2. Set breakpoint on _start.
3. Nexti until you reach the appropriate call, then issue stepi.
4. You are now at your code.
Some odd things here. When TUI starts up, your code is displayed with
no labels, despite compiling with "-g". The startup code has labels.
For reference, here is the assembler.
/*
* Calling printf via assembler.
*
*/
.section ".data"
hello: .asciz "Hello, World!\n"
.global main
.align 4
main:
save %sp,-96,%sp
set hello,%o0
call printf
nop
mov 0,%i0
ret
restore
