Switched gshare to use an integer parameter to select between gshare and global.

0b9fd8a4b3 Fixed Issue #106: fld rasies load access fault instead of illegal instruction. The IEU controller had considered all fp loads and stores to be legal regardless of whether the FPU is enabled or the type is supported. Merged illegal instruction detection from both units into the Decode stage, saving two bits of pipeline register as well. 2023-02-21 09:32:17 -08:00
