| Setting Name: | hal.enable_c_plus_plus |
| Identifier: | ALT_NO_C_PLUS_PLUS |
| Default Value: | 1 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Enable support for a subset of the C++ language. This option increases code footprint by adding support for C++ constructors. Certain features, such as multiple inheritance and exceptions are not supported. If false, adds -DALT_NO_C_PLUS_PLUS to ALT_CPPFLAGS in public.mk, and reduces code footprint. |
| Restrictions: | none |
| Setting Name: | hal.enable_clean_exit |
| Identifier: | ALT_NO_CLEAN_EXIT |
| Default Value: | 1 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | When your application exits, close file descriptors, call C++ destructors, etc. Code footprint can be reduced by disabling clean exit. If disabled, adds -DALT_NO_CLEAN_EXIT to ALT_CPPFLAGS -D'exit(a)=_exit(a)' in public.mk. |
| Restrictions: | none |
| Setting Name: | hal.enable_exit |
| Identifier: | ALT_NO_EXIT |
| Default Value: | 1 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Add exit() support. This option increases code footprint if your "main()" routine does "return" or call "exit()". If false, adds -DALT_NO_EXIT to ALT_CPPFLAGS in public.mk, and reduces footprint |
| Restrictions: | none |
| Setting Name: | hal.enable_gprof |
| Identifier: | ALT_PROVIDE_GMON |
| Default Value: | 0 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |

| Setting Name: | hal.enable_lightweight_device_driver_api |
| Identifier: | ALT_USE_DIRECT_DRIVERS |
| Default Value: | 0 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Enables lightweight device driver API. This reduces code and data footprint by removing the HAL layer that maps device names (e.g. /dev/uart0) to file descriptors. Instead, driver routines are called directly. The open(), close(), and lseek() routines will always fail if called. The read(), write(), fstat(), ioctl(), and isatty() routines only work for the stdio devices. If true, adds -DALT_USE_DIRECT_DRIVERS to ALT_CPPFLAGS in public.mk. |
| Restrictions: | The Altera Host and read-only ZIP file systems can't be used if hal.enable_lightweight_device_driver_api is true. |
| Setting Name: | hal.enable_mul_div_emulation |
| Identifier: | ALT_NO_INSTRUCTION_EMULATION |
| Default Value: | 0 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Adds code to emulate multiply and divide instructions in case they are executed but aren't present in the CPU. Normally this isn't required because the compiler won't use multiply and divide instructions that aren't present in the CPU. If false, adds -DALT_NO_INSTRUCTION_EMULATION to ALT_CPPFLAGS in public.mk. |
| Restrictions: | none |
| Setting Name: | hal.enable_reduced_device_drivers |
| Identifier: | ALT_USE_SMALL_DRIVERS |
| Default Value: | 0 |
| Value: | 1 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Certain drivers are compiled with reduced functionality to reduce code footprint. Not all drivers observe this setting. The altera_avalon_uart and altera_avalon_jtag_uart drivers switch from interrupt-driven to polled operation. CAUTION: Several device drivers are disabled entirely. These include the altera_avalon_cfi_flash, altera_avalon_epcs_flash_controller, and altera_avalon_lcd_16207 drivers. This can result in certain API (HAL flash access routines) to fail. You can define a symbol provided by each driver to prevent it from being removed. If true, adds -DALT_USE_SMALL_DRIVERS to ALT_CPPFLAGS in public.mk. |
| Restrictions: | none |
| Setting Name: | hal.enable_runtime_stack_checking |
| Identifier: | ALT_STACK_CHECK |
| Default Value: | 0 |
| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Turns on HAL runtime stack checking feature. Enabling this setting causes additional code to be placed into each subroutine call to generate an exception if a stack collision occurs with the heap or statically allocated data. If true, adds -DALT_STACK_CHECK and -fstack-limit-register=et to ALT_CPPFLAGS in public.mk. |
| Restrictions: | none |

| Value: | 0 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | The BSP is compiled with optimizations to speedup HDL simulation such as initializing the cache, clearing the .bss section, and skipping long delay loops. If true, adds -DALT_SIM_OPTIMIZE to ALT_CPPFLAGS in public.mk. |
| Restrictions: | When this setting is true, the BSP shouldn't be used to build applications that are expected to run real hardware. |
| Setting Name: | hal.enable_small_c_library |
| Identifier: | none |
| Default Value: | 0 |
| Value: | 1 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Causes the small newlib (C library) to be used. This reduces code and data footprint at the expense of reduced functionality. Several newlib features are removed such as floating-point support in printf(), stdin input routines, and buffered I/O. The small C library is not compatible with Micrium MicroC/OS-II. If true, adds -msmallc to ALT_LDFLAGS in public.mk. |
| Restrictions: | none |
| Setting Name: | hal.enable_sopc_sysid_check |
| Identifier: | none |
| Default Value: | 1 |
| Value: | 1 |
| Type: | Boolean |
| Destination: | public_mk_define |
| Description: | Enable SOPC Builder System ID. If a System ID SOPC Builder component is connected to the CPU associated with this BSP, it will be enabled in the creation of command-line arguments to download an ELF to the target. Otherwise, system ID and timestamp values are left out of public.mk for application Makefile "download-elf" target definition. With the system ID check disabled, the Nios II EDS tools will not automatically ensure that the application .elf file (and BSP it is linked against) corresponds to the hardware design on the target. If false, adds --accept-bad-sysid to SOPC_SYSID_FLAG in public.mk. |
