以下的TYPE = DSECT是什么意思？有什么影响？
.reset : > RESET, PAGE = 0, TYPE = DSECT
vectors : > VECTORS PAGE = 0, TYPE = DSECT
看过《TMS320C28x Assembly Language Tools V6.1》中7.5.8 Special Section Types (DSECT, COPY, and NOLOAD)的描述，但没看明白，这几个是什么意思？有什么区别和影响？
注：SECTIONS之前已有

Young Hu：
The DSECT type creates a dummy section with the following characteristics:– It is not included in the output section memory allocation. It takes up no memory and is not includedin the memory map listing.– It can overlay other output sections, other DSECTs, and unconfigured memory.– Global symbols defined in a dummy section are relocated normally. They appear in the outputmodule's symbol table with the same value they would have if the DSECT had actually beenloaded. These symbols can be referenced by other input sections.– Undefined external symbols found in a DSECT cause specified archive libraries to be searched.– The section's contents, relocation information, and line number information are not placed in theoutput module.

这部分我以前看过，但始终不明白什么意思。
.reset : > RESET, PAGE = 0, TYPE = DSECTvectors : > VECTORS PAGE = 0, TYPE = DSECT
由It is not included in the output section memory allocation. It takes up no memory and is not included in the memory map listing.加上The section's contents, relocation information, and line number information are not placed in theoutput module.，是否指这两个段并没有装载？
那Global symbols defined in a dummy section are relocated normally. They appear in the output module's symbol table with the same value they would have if the DSECT had actually been loaded. These symbols can be referenced by other input sections.又指什么？
说到底，dummy section 到底是什么？
