CC equivalent of security related switchs

Question

Hi,
Are there any compiler or linker options that perform similar to:
1) Buffer overflow detection (Microsoft's /GS and GNU's -fstack-protector)
2) Prevent data execution (Microsoft's /NXCOMPAT)
3) Position independent executables ( Microsoft's /DYNAMICBASE and GNU's -fpie)
I'm using Solaris Studio 12.2 and not seeing anything in the compiler's documentation. Are there any recommendations hardening executables during the build process? Thanks for any help.

Hi,
These might be what you're after:
1) -xcheck=stkovf
You should look at using using discover for memory access error detection, the stack overflow checking only checks for running out of stack space, not errors in accessing data held on the stack.
2) -M /usr/lib/ld/map.noexdata
This is a linker mapfile that makes the data segment non-executable.
3) -xcode=pic32
Generates 32-bit position independent code.
HTH,
Darryl.
