How to declare en function import

[sauron_le_noir]

I try to program a hello world in mips assembler. But i'm in trouble how to declare a import function in my program. When psp-fixup-imports is executed i've received a
Error, invalid stub address.

The Makefile

Code: Select all

PSPSDK = $(shell psp-config --pspsdk-path)
PSPLIBSDIR = $(PSPSDK)/..
TARGET = hellomips
OBJS = hellomips.o
CFLAGS = -O2 -G0 -Wall -mno-crt0 -nostartfiles -nostdlib -nodefaultlibs
ASFLAGS = $(CFLAGS)
BUILD_PRX=1
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Hello World

include $(PSPSDK)/lib/build.mak

the macs.s file

Code: Select all

	.macro IMPORT_START module, flags_ver
	.set push
	.section .rodata.sceResident, "a"
	.word   0
__stub_modulestr_\module:
	.asciz  "\module"
	.align  2

	.section .lib.stub, "a", @progbits
	.global __stub_module_\module
__stub_module_\module:
	.word   __stub_modulestr_\module
	.word   \flags_ver
	.word   0x5
	.word   __executable_start
	.word   __executable_start

	.set pop
        .endm

        .macro IMPORT_FUNC module, funcid, funcname

	.set push
	.set noreorder

	.extern __stub_module_\module
	.section .sceStub.text, "ax", @progbits
	.globl  \funcname
	.type   \funcname, @function
	.ent    \funcname, 0
\funcname:
	.word   __stub_module_\module
	.word   \funcid
	.end    \funcname
	.size   \funcname, .-\funcname

	.section .rodata.sceNid, "a"
	.word   \funcid

	.set pop
        .endm

        .macro IMPORT_FUNC_WITH_ALIAS module, funcid, funcname, alias

	.set push
	.set noreorder

	.extern __stub_module_\module
	.section .sceStub.text, "ax", @progbits
	.globl  \alias
	.type   \alias, @function

	.section .rodata.sceNid, "a"
	.word   \funcid

	.set pop
        .endm

the moduleinfo.s

Code: Select all

	.globl	module_info
	.section .rodata.sceModuleInfo,"a",@progbits
	.align	4
module_info:
	.half	0
	.byte	1
	.byte	1
	.ascii	"Hello world\000"
	.space	15
	.byte	0
	.word	_gp
	.set push
        .section .lib.ent.top, "a", @progbits
        .align 2

        .set pop
        .text

and finaly the main program hellomips.s

Code: Select all

	.include "mac.s"
