[edk2-devel] question about MSFT compiler/link option

[Tiger Liu(BJ-RD)]

Hi, Experts:
I have a question about MSFT compiler/link option.

I wrote a PEIM, which had a large global data array definition in a C file.
Such as:
PRI_DATA_STRUCT  PdataStructTable[] = {
{01,           0x75,    0xF0,     0x0,     0x0,     0x0 },
{02,           0x77,    0xF0,     0x0,     0x0,     0x0 },
{03,           0x79,    0xF0,     0x0,     0x0,     0x0 },
{04,           0x7B,    0xF0,     0x0,     0x0,     0x0 },
{05,           0x7D,    0xF0,     0x0,     0x0,     0x0 },
{06,           0x7F,    0xF0,     0x0,     0x0,     0x0 },
......
};

This global data array is very large, about 20KB.

But I found the PEIM's compiled size is about 5KB, it seems not include this global data array in the efi binary statically.
Even the release version PEIM's size is larger than debug version.

I found when compiling release version, the link option has : /MERGE:.rdata=.data
It seems release binary included the global data array in the final efi image.

So, my question is:
Will the global data array be in linked into the final efi binary image when compiling debug version?

Thanks
