Ghidra: Decompiler exception
I see the following message in the "Decompiler window:
Exception while decompiling xxxxx: Decompiler results exceeded payload limit of 50 MBytes
is there an easy way to allow more payload ?
Rather than use an indexed table the coders decided to go for several hundred statements similar to the following to print various messages...
if (r4 == 0x2c) goto loc_xyz;
some of them are nested, which is why I think the code breaks the de-compiler.
if (r4 != 0x98) {
if (r4 != 0x93) {
if (r4 != 0x94) {
if (r4 != 0x95) {
if (r4 != 0x96) {
if (r4 != 0x97) {
if (r4 != 0x9d) {
if (r4 != 0x9e) {
if (r4 != 0xa4) {
if (r4 != 0xa8) {
if (r4 != 0xab) {
if (r4 != 0xac) {
if (r4 != 0xad) {
Etc...
"hopper dissasembler" just about manages to break the code down, but ghidra breaks.

To increase the payload size:
Edit->Tool Options->Decompiler->Decompiler Max-Payload (from the Code Browser).

Thanks guys..
300mb got it..........
The funny thing is that it's not a lot of code when its done. (3245 lines).
Clearly it's just badly nested (most of which seems to optimize out on the de-compile)
It looks like one of those things where it's evolved over years & just kept having exceptions added.
