Supported architectures

During the analysis, TrustInSoft CI faithfully emulates a target hardware architecture, respecting properties such as endianness, integer types and alignment constraints.

For each analysis, you can specify the target architecture of your choice by setting the machdep field in the Analyses configuration file to the corresponding architecture name. If machdep is not provided, TrustInSoft CI emulates, by default, a 32-bit x86 processor.

See below the list of currently supported architectures or read more about machdep.

Supported architectures

The table below provides a high-level description and the endianness of each supported architecture. To get further information on the data types, visit the Fundamental data types section.

With the exception ofapple_ppc_32, x86_win32 andx86_win64, all target architectures may be specified with the gcc_ prefix, in which case gcc language extensions are allowed, and the__int128integer type is available on a 64-bitmachdep.

Architecture name in machdep	Endianness	Description
x86_16	Little	An x86 processor in 16-bit mode, in “tiny” or “small” memory model (using 16-bit “near” pointers). The long double type is the 80387 80-bit native format.
x86_16_huge	Little	An x86 processor in 16-bit mode, in “large” or “huge” memory model (using 32-bit “far” pointers). The long double type is the 80387 80-bit native format.
x86_32	Little	An x86 processor in 32-bit mode. The long double type is the 80387 80-bit native format.
x86_win32	Little	An x86 processor in 32-bit mode, using the Win32 ABI.
x86_64	Little	An x86-64 processor in 64-bit mode. The long double type is the IEEE754 quad-precision type.
x86_win64	Little	An x86 processor in 64-bit mode, using the Win64 ABI. The long type is 32 bits.
ppc_32	Big	A 32-bit PowerPC processor. The char type is unsigned; the long double type is the IEEE754 quad-precision type.
ppc_64	Big	A 64-bit PowerPC processor. The char type is unsigned; the long double type is the IEEE754 quad-precision type.
apple_ppc_32	Big	Same as ppc_32, but forcing the “char” type to be signed, as done by the Apple toolchain (as opposed to the default PowerPC use of unsigned char type), and allowing gcc language extensions.
arm_eabi	Little	A 32-bit ARM processor, using the extended ABI (EABI). The char type is unsigned.
armeb_eabi	Big	A 32-bit ARM processor, using the extended ABI (EABI). The char type is unsigned.

aarch64eb	Big	A 64-bit ARMv8 processor (AArch64). The char type is unsigned; the long double type is the IEEE754 quad-precision type.
sparc_32	Big	A 32-bit SparcV8 processor.
sparc_64	Big	AA 64-bit SparcV9 processor. The long double type is the IEEE754 quad-precision type.
