5.3 Setting Stack Size from gnatlink

It is possible to specify the program stack size from gnatlink. Assuming that the underlying linker is GNU ld there is two ways to do so:

• using -Xlinker linker option

  $ gnatlink hello -Xlinker --stack=0x10000,0x1000

  This set the stack reserve size to 0x10000 bytes and the stack commit size to 0x1000 bytes.

• using -Wl linker option

  $ gnatlink hello -Wl,--stack=0x1000000

  This set the stack reserve size to 0x1000000 bytes. Note that with -Wl option it is not possible to set the stack commit size because the coma is a separator for this option.
