If I do like this then it works: EUROASM CPU=X64 TestDLL PROGRAM FORMAT=DLL, MODEL=FLAT, WIDTH=64 EXPORT foo foo PROC RET ENDP foo align 16 EXPORT bar bar PROC RET ENDP bar ENDPROGRAM TestDLL It works, because at the time of align 16 €ASM already encountered code instructions foo PROC and RET , whi...

I have to praise you, Andrey, for the perfect minimal verificable example. Rather then WinDbg I am using OllyDbg for 32bit programs, see the enclosed snapshot. It reveals that the the exception was raised by reading from NUL pointer at 0x0041497d in the procedure PseudoALIGN , below the instruction ...

No, you didn't miss anything; according to the description in SHUFPS , shuffle instructions use imm8[1:0], imm8[3:2], imm8[5:4], imm8[7:6] and the value of immediate operand 0..255 is legal. I must have misunderstand the selection mechanism of the third operand years ago :oops: This bug will be fixe...

phpBB was updated to verzion 3.3.12 today.

However, that means if only a very small UMB is available, you may fail to allocate it when it is between 144 and 288 Bytes in size, even though that would suffice to install the resident portion. I thought it necessary to tell DOS that PSP of the resident has changed (was moved to upper memory). T...

On 2023/09/08 ecm says at Stack Overflow : In your tsrup example, it is said that a UMB must be allocated OFFSET# TsrTop - Shift bytes. However, the AllocUMB function is called with MOV CX,OFFSET# TsrTop / 16 so it appears to allocate too much. Is this an oversight in your example, or am I mistaken?...

Hi, nice to read this. Uint8ToFloat real4 255.0, 255.0, 255.0, 255.0 > Uint8ToFloat: DD 255.0, 255.0, 255.0, 255.0 (tried Uint8ToFloat: DO..., but euroasm told me that the Oword memory variable cannot be statically initialized.) Actually not directly with one value but this can be bypassed with spec...

Hello Andrey, there is a way but not much elegant and I had to omit MASM directives for SEH (Structured Exception Handling) which are not supported by €ASM: ;------------------------------------------------------------------------- ; Description: The following macro generates code that creates a sta...
