but I used to work with ARM7TDMI and I think that did not have BLX, and here ARM states that "This instruction is available in all T variants of ARM architecture v5 and above."
Shouldn't it then be "ARMv5T+" in both cases? "bx register" seems to be correct.

armdata.js marks "blx label" as available in ARMv4:
["blx" , "#RelS*4" , "T32", "1111|0|RelS[22]|RelS[19:10]|11|Ja|0|Jb|RelS[9:0]|0" , "ARMv4T+ IT=OUT|LAST"],["blx" , "#RelS*2" , "A32", "1111|101|RelS[0]|RelS[24:1]" , "ARMv4+"],but I used to work with ARM7TDMI and I think that did not have BLX, and here ARM states that "This instruction is available in all T variants of ARM architecture v5 and above."
