04/13/17 10:47:54, Michael Van Canneyt : > Dynamic Packages will in each case be optional, they will not be not mandatory. The main question is a bit different. Is performance penalties from Dynamic Packages will be optional? I try show example. Let's provide that we

[fpc-devel] Discussion about "Dynamic packages"

I had some fears concerning idea development of "Dynamic packages" in FreePascal and possible performance penalties of programs from these changes. This why i start this discussion and try wrote some of my ideas or/and proposal that, as i think, can help make FreePascal better. At first I

[fpc-devel] Some questions about compiler work on x86_64-win64

I have some questions about compiler work on x86_64-win64. 1) EXE-file contained .CRT section. As i understand it contained one pointer to _FPC_Tls_Callback functions from RTL. Is it used only for this? 2) Why INITFINAL table on both Windows and Linux puted to .data section? Is we need to

[fpc-devel] How to get pointer to class VMT in assembler block

I need to get pointer to class VMT in assembler block. In pascal code this can be done very simple, like Ptr := Pointer(SomeClass). But when i try in assembler do like "MOV RAX, SomeClass" this make assembler syntax error. If i try "LEA RAX, [SomeClass]" this compiled like "LEA RAX, [0]".

[fpc-devel] x86ins.dat bytes format description

Hi all. I am working on adding support of TSX instructions to FPC compiler. So i need modify x86ins.dat. In sections "bytes" this file contains not only opcode byte. In aditional it contains some control codes that describe generation of prefixes, schema of operands coding and etc. In some
