 # SYNOPSIS

 #   AX_GCC_X86_CPUID(OP)

 #
 # DESCRIPTION
 #
 #   On Pentium and later x86 processors, with gcc or a compiler that has a
 #   compatible syntax for inline assembly instructions, run a small program
 #   that executes the cpuid instruction with input OP. This can be used to
-#   detect the CPU type.
+#   detect the CPU type. AX_GCC_X86_CPUID_COUNT takes an additional COUNT
+#   parameter that gets passed into register ECX before calling cpuid.
 #
 #   On output, the values of the eax, ebx, ecx, and edx registers are stored
 #   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
