Architectures In Guile (Debugging with GDB)

23.4.3.21 Guile representation of architectures

GDB uses architecture specific parameters and artifacts in a number of its various computations. An architecture is represented by an instance of the <gdb:arch> class.

The following architecture-related procedures are provided by the (gdb) module:

Scheme Procedure: arch? object; Return #t if object is an object of type <gdb:arch>. Otherwise return #f.

Scheme Procedure: current-arch; Return the current architecture as a <gdb:arch> object.

Scheme Procedure: arch-name arch; Return the name (string value) of <gdb:arch> arch.

Scheme Procedure: arch-charset arch; Return name of target character set of <gdb:arch> arch.

Scheme Procedure: arch-wide-charset; Return name of target wide character set of <gdb:arch> arch.

Each architecture provides a set of predefined types, obtained by the following functions.

Scheme Procedure: arch-void-type arch; Return the <gdb:type> object for a void type of architecture arch.

Scheme Procedure: arch-char-type arch; Return the <gdb:type> object for a char type of architecture arch.

Scheme Procedure: arch-short-type arch; Return the <gdb:type> object for a short type of architecture arch.

Scheme Procedure: arch-int-type arch; Return the <gdb:type> object for an int type of architecture arch.

Scheme Procedure: arch-long-type arch; Return the <gdb:type> object for a long type of architecture arch.

Scheme Procedure: arch-schar-type arch; Return the <gdb:type> object for a signed char type of architecture arch.

Scheme Procedure: arch-uchar-type arch; Return the <gdb:type> object for an unsigned char type of architecture arch.

Scheme Procedure: arch-ushort-type arch; Return the <gdb:type> object for an unsigned short type of architecture arch.

Scheme Procedure: arch-uint-type arch; Return the <gdb:type> object for an unsigned int type of architecture arch.

Scheme Procedure: arch-ulong-type arch; Return the <gdb:type> object for an unsigned long type of architecture arch.

Scheme Procedure: arch-float-type arch; Return the <gdb:type> object for a float type of architecture arch.

Scheme Procedure: arch-double-type arch; Return the <gdb:type> object for a double type of architecture arch.

Scheme Procedure: arch-longdouble-type arch; Return the <gdb:type> object for a long double type of architecture arch.

Scheme Procedure: arch-bool-type arch; Return the <gdb:type> object for a bool type of architecture arch.

Scheme Procedure: arch-longlong-type arch; Return the <gdb:type> object for a long long type of architecture arch.

Scheme Procedure: arch-ulonglong-type arch; Return the <gdb:type> object for an unsigned long long type of architecture arch.

Scheme Procedure: arch-int8-type arch; Return the <gdb:type> object for an int8 type of architecture arch.

Scheme Procedure: arch-uint8-type arch; Return the <gdb:type> object for a uint8 type of architecture arch.

Scheme Procedure: arch-int16-type arch; Return the <gdb:type> object for an int16 type of architecture arch.

Scheme Procedure: arch-uint16-type arch; Return the <gdb:type> object for a uint16 type of architecture arch.

Scheme Procedure: arch-int32-type arch; Return the <gdb:type> object for an int32 type of architecture arch.

Scheme Procedure: arch-uint32-type arch; Return the <gdb:type> object for a uint32 type of architecture arch.

Scheme Procedure: arch-int64-type arch; Return the <gdb:type> object for an int64 type of architecture arch.

Scheme Procedure: arch-uint64-type arch; Return the <gdb:type> object for a uint64 type of architecture arch.

Example:

(gdb) guile (type-name (arch-uchar-type (current-arch)))
"unsigned char"
