Can you find out which compiler was used to compil

Question

Given an executable that is compiled from C to run on Solaris, is it possible to determine which compiler was used to compile the associated incomplete executable?

I can't see anything when using either the strings or the file command, and magic doesn't seem to contain anything specific.

Do compilers generally put a fingerprint in their executable output files?

cheers,

Not stripped:

$ cc -O hello.c

$ file a.out

a.out: ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, dynamically linked, not stripped

$ strings -a a.out | grep cc

/opt/solarisstudio12.3/prod/bin/cc -O hello.c

$ dwarfdump -i a.out | grep compile_o

DW_AT_SUN_compile_options Xa;O;R=Sun C 5.12 SunOS_sparc Patch 148917-07 2013/10/18;backend;raw;cd;

Stripped:

$ strip a.out

$ file a.out

a.out: ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, dynamically linked, stripped

$ strings -a a.out | grep cc

(none)
