Hi.
I've been trying to build aes-armv4 for an embedded ARM 9 using the Green Hills
Software tools. In the FIPS canister, the line following the label .Lok ...
.Lok: stmdb sp!,{r4-r12,lr}
sub r10,r3,#fips_aes_set_encrypt_key-AES_Te-1024 @ Te4
gets this error:
[asarm] (error) ..\Src\fips\crypto\aes\asm\aes_armv4.arm 374:
expected a register sub r10 , r3 , fips_aes_set_encrypt_key - AES_Te - 1024
Green Hills support says:
>From what I'm seeing the form of the instruction you are using requires that
>the constant fit in an 8-bit sized field. The constant expression:
fips_aes_set_encrypt_key-AES_Te-1024
currently resolves to:
0xb6c-0-0x400 = 0x76c
which does not fit in an 8 bit field.
Could I have made an error in my port which could explain this? If this file
was successfully built using some ARM compiler, which one was it?
Thanks very much,
Paul
